What do you think of these packs?

I own Growing Together but not Home Chef Hustle. I'll give you a shorter reply than you hope for; I just realized that many of the features you ask about I never really noticed in my game. Then I understand that these crises etc are probably more fun and meaningful if you play one household over time. I play rotationally, so I probably miss most of that.

I like the pack though. World suits me well, I added Recreation Centers as regional community centers in all my 8 regions and the places are always busy. B/B is fine too, CAS is good although a bit weird in a different sort of homey way (which I use quite a lot), and the Infants are just so extremely cute, again probably more fun if staying with one family for a while to see development, but I really like them although I do not focus a lot on their life stage.

So - if you play rotationally and there are other packs you do not own, I'd consider other packs before this one.

Ok, that's a lot of questions, I'll try to answer most of them.

The aspirations in both packs are nice. They're still Sims 4 aspirations, but they're enjoyable, and it's good to have more variety for kids. I have only tried one of the Home Chef Hustle ones, but it didn't feel too much like a tutorial, as it did have some objectives which, while easy, required some set up.

Burnout, in my opinion, is much less annoying than the fears, and in fact, I think it has added to my gameplay (a little) by reminding me to vary a sims' activities when I start getting a little one-track. You get a warning with a little moodlet, which can be cleared by doing something else for a few hours, and if you do get into burnout (there are two stages of this, if I'm not mistaken), taking a day off or two to focus on other things clears it. Burnout really doesn't happen randomly and it's easy enough to manage not to get to the full thing that really hinders skill building and career leveling. Having sims do relaxing activities or sports clears up the moodlets, as does doing activities opposite what brought on the burnout (creatives skills or "mental" activities). 

Midlife crisis is pretty easy to ignore if you don't like it. Only some sims will get it. It gives your sim a +1 tense moodlet and a small buff to facilitate doing new things, and can give some extra, bigger moodlets at times (but positive and negative). You get some extra goals that reward satisfaction points and fulfilling enough to resolve the crisis (which also resolves on its own after a few days) gives the sim a happy moodlet.

I haven't really had any annoyances with Growing Together so far. I think the milestones are fine, but I rarely check them and barely ever rotate to other families at the moment, so I wouldn't have noticed. 

Family dynamics and compatibility seem to affect the game quite a bit. Dynamics change the sims autonomous behaviors and compatibility can make it easier or harder to make friends, though it's nothing unbearable. You can also just refuse any family dynamic the game suggests that you don't like, so it never gets in the way of my stories. 

As for B/B in Growing Together, it's simple enough to go well with most things. I'm not 100% sure about color matching and such because I use a lot of packs together. Some furniture goes particularly well with the mid-century stuff from Get Famous, and there's some craftsman stuff that pairs well with Seasons. And of course, Parenthood, considering the amount of children's stuff in the pack. 

As for Home Chef hustle, the appliances are nice. They're quick and easy to use, allowing sims to do short tasks while they work (haven't tried the pizza oven yet, though). The build buy stuff, other than the counters and cabinets, is mostly kitchen clutter and appliances, so it goes well with just about anything. The pack has a pretty modern feel, and I use the wallpapers a lot. 

I hope this helps! 

Growing Together

-Honestly all Aspirations are just the same 'do thing to check off said thing' you know? But I think it was fine to be doing and nothing too complicated. More aspirations for kids was something I enjoyed.

-There's no way to turn off burnout unless you mod it out. I haven't gotten a lot of burn out lately like when it first came out. Use to get it every other sim day or so seems like I get it maybe once a sim week or so. So depends. Can offset it with having a sim relax to get that moodlet down. Found it easy since I have the Spa Day pack.

-Can't turn off Midlife Crisis, BUT your sim can go get counseling so your sim don't have to do that (Like my sim wanted to get divorced, went to pay out the money and no more with that)

-Not sure what you mean 'ideas' less you mean gameplay elements that came with the day. Only thing I've found to be mildly annoying is the clipping with child sims learning to ride a bike if there's not enough room. Haven't had much problems out of this pack really. Other than when there was a problem with the whole kids losing a tooth, but that's fixed.

-Yes, they fixed the milestones haven't had any missing milestones at all.

-Quite a lot. Sims can get along with one another well, slightly or just down right have a hard time getting to know one another because they have different likes and dislikes. Which I enjoyed watching relationships build slower or just not at all if they don't like one another. Dynamics in family I definitely enjoy especially since they can change if sims put effort into their relationships. Like I Bob and Eliza's relationship? I put it as distant. Can definitely tell the difference with how most of their conversations don't go so well in the least even with having a green bar. Sometimes it seemed like they weren't talking to each other often at all. Sims definitely don't seem interested in talking with other sims they don't like nor have pleasant conversations without the affects of a red bar. About the same with romantic dynamic focusing on the romance part which was strained as I had them. Like there were attempts. Can be changed if you guide them to work on it if they don't do it themselves.

-The build buy is nice to me. Far as furniture style falls into basics/contemporary styles with a few others sprinkled in. Think It's go well with Parenthood and Highschool years definitely along some other pieces in other packs.

Chef Hustle

-They're okay only prefer the one where you have to run a food stall since it doesn't feel like I'll go through it too quickly.

-I like the new appliances. (Been forever to get any until we got different ones from For Rent) Think the waffle maker and stand mixer are my favorite. The latter you can even eat the prepared ingredients you need for other recipes as is. Though sims have a habit of eating those like leftovers all the time. The pizza oven is nice, but think I only have it outside for sims to use for the most part at home or at a business to sell.

-Contemporary, but modern look. Lot of clutter for the most part in decor which would pair with the above packs mentioned earlier. Fridge, oven and counters definitely blocky look to it.

They have not fixed the milestones. When you go off to play another household, the infants are at ground zero. However, when you go back into that household, the milestones are there. It would be nice if the infants could crawl if you play a different household and you invite them over, but no fix yet. 

I love all the appliances that come with Home Chef Hustle. I did make a pizza parlor with my Dine Out and unfortunately those special pizzas are not used for Dine Out. 

I had the most fun with home chef hustle initially.  Growing Together was a little lack luster for me at first,  as family game play is not my style and this pack was broken in may ways for me at first.  Only recently has the pack shown itself to me to be worth it,  but you can only see it through a lot of family gameplay.  It's kind of worked in.  Also since I got for rent a new found love of the world as finally prefect places for my painted ladies townhouses.

childhood aspirations fun- dont know- I tried the building tree thing first but it was broken for me.  I dont play as children often.

Burnout looks like Fear of Dead End Job- hate the idea of- never happened- not something I do not play the sims for- escapist here.

Midlife Crisis looks like a bummer. - kind of cute-  get to play sims in a different way than you set up.  I liked it. Kind of realistic. It's not in a bummer way.

"fun game play" -  yes.  my baby infant Hope just learned to crawl and that was the highlight of my gamplay after so long practicing with her.  I also so her almost stand by herself at the church,  she got up on her pew by herself.

Never had a problem with milestones disappearing and I am heavy in rotation in my game play style.

I like the family dynamics added and compatibility added but I am not sure how it affects the game play.

I certain items from the build buy I am always using.  While it's not my favorite style the bathtub with the glass doors which is a modern day stable and I cant believe the did n' add it until now is available with this pack.  There are a lot of nice windows but I use them in builds that are anything but San Sequoia,  very nice kitchen appliances- possibly among the best, and a couple more items I always use.  They seamlessly match well with other packs.  Big reason to buy this pack though is the infant items and milestones,  if you're into that.  I'm usually not into that,  but with this game pack I found myself very into it.

Hope chef hustle is a lot of fun,  I really enjoyed the gameplay and build buy. It is like it's price point,  a bit of get it all out in a week or two,  where GT takes more time to understand how it affects your game and will continue to influence your game in a subtle longer way.

Hope finally crawling after a training for a bit.  She also kind of almost stand by herself is the most rewarding moments from this pack for me.

The appliances in Home Chef Hustle are great if you want to play rags to riches because they basically amplify the ingredients. Add 1 bag of flour in the mixer and get 5 dough batters so you can cook five dishes with that. In this regard it's great if your sims cooks a lot for sale, or is low on food ingredients. But for everyday use I find it a bit annoying to first make the batter and then cook the waffles and then there is leftover batter in the the fridge that will probably be spoilt because if they eat too many waffles they get the junk food lifestyle. I really wished it mattered more how many fish we caught or how many vegetables we harvested, because there isn't much else to do with these things except sell them.

OMG! Just get both. 🤪They go together. Food blends with everything and I'm cooking more food in my game right now then at work...

I'm a pastry chef in the real and I can't get over the food in this game. I do have a realistic food mod in my game that is base game with no conflicts with other mods. 

My sims are making a lot of money selling food in this game and I love it!!

I also enjoy family play. My favorite age to play is young adult and child age...Seniors  are next.

Growing Together is like a glue that connects all the family gameplay. Families love to eat!

I bought and explored Growing Together because of all the families and children in my game. I'm not disappointed  so far. 

I would buy both if you want to run a family restaurant.  🙂

If you want to play "raising a child", Growing Up Together is so much fun.   You don't just dress children, you teach them through activities.  Each new phase (Toddler, Child) builds on the skills from the previous stage.  The childhood aspirations are great fun; you have to balance the toddler/child's needs, wants, and education.

I will say,  it doesn't go well with Go To Work.  I miss a lot of days with my Sim child because I'm off saving lives at the hospital.  As usual, nannies are useless.

Whoever introduced milestones never conisdered rotational gameplay. They fixed part of it. If you rotate households they will still be there if you rotated back to a household. but unforturantly milestones of families who are currently not your played household don't have them. Which is very annoying for infanct. If you can and want to use mods, there is a fix to adress this issue.

I don't own Home Chef Hustle yet, probably will one day, but I haven't had use for it yet (I tend to buy the smaller packs only when I have a sim that fits the story, unless there is really good CAS or BB that I want). 

As for Growing Together I personally love it. The family dynamics is fun (just be careful with "strict" it's very annoying), the milestones are something that makes a life make sense (although I wish there were more, and that the crawling one didn't take so long. It's nearly impossible). As for them disappearing, not anymore, at least not for me and I do play rotationally. The infants are adorable and the new sleep over options fun. I love that family can make surprise visits. As for your questions, the burn-out as mentioned by others are easy to deal with and no big deal, just do something else or go on a vacation for a day or two before it gets bad. The midlife crisis can be a fun way to push out of your comfort zone and if you don't like it ignore it easily enough. As for combability it doesn't affect the game nearly enough, the sims still make friends very easily.
