Which pack next?

Of the packs you mentioned, Cottage Living and Werewolves are the best!

My definite favour is Wolvies, it is fun and the angry hairy Sims make it a challenge to play!

I do like both the Werewolf and High School pack almost equally. With a world (werewolf) that has almost no loading screens, only when just entering into different lots, you can walk around the whole town with no loading screen. I do like the library and gym combo in the town.

With High School I really love how they added more to the teen life stage, now I only hope they do the same for elementary kids.

As far as the world that came with the high school pack, I can't really go into much detail, because I haven't really gotten a chance to delve into it much yet.

Werewolves is the one must have on your list for me. It is really well done and it's still as much fun two months later as it was on day one. It's also one of the least buggy packs in a while, and is one of my all time favorites. I'm a bit of a werewolf fan girl so I am biased.

Of the others, I'd go with Dream Home Decorator. I think the BB is great and the CAS stuff is fairly good too. The interior decorator career I really can't say much about because I've played it twice and not for very long. It's one that I keep saying I want to go back and try but I haven't so far. What I did see of it felt like it would be fun if I was in the right mood to take it on.

I love Tartosa but I'm not sure I'd recommend MWS just for that when there are still some better packs that you don't already have. Even though HSY fits your style the best, I'd give it a bit more time for patches and mods to fix it up. I have a hard time figuring out how many of the bugs were the fault of the pack or that train wreck of an update. Personally I feel like from my own experience with the pack that it's more the update that broke things. Either way I'd give it a couple more months before I came back to it if I didn't already have it. It's one of the rare times I regret getting a pack or kit on day one or soon after. I wish I had waited a couple of months like I did with MWS.

Werewolves--I'm not a fan of occults and if were up to me I'd be just fine if we never had them, but I'm the type that buys every pack so I got it, tried it, loved it! I was so surprised how much I loved this one and I was not ready for HSYs because I was still loving this one.

My Wedding Stories--Even though this was patched, it's still broken. If it worked properly it probably would be a really cute pack.

Dream Home Designer--This one is great because of all the cute new objects, but the new career is fun to play too.

High School Years--This one got old for me real fast. There's only so many times you can go to school, go to prom, graduate. And while the pier is pretty cute, rabbit hole rides get old pretty fast too.

High school might get boring, but you have the option to just send the sim alone.

I'd suggest werewolves for one simple reason. They intrigue you even though you don't typically play with occult sims. IMHO they are the best laid out occult for sims 4. In sims 2 I'd have said Vampires, in three I'd have said aliens. But If they are intriguing enough to you to allow you to consider getting them even though you are not a big occult sim fan, I'd say its the right choice. Hope I helped.

Personally, I like all the ones you've listed for different reasons.

I haven't played a lot with Werewolves. I'm generally not an occult player but I like having the option. The Build/Buy is pretty cool, if you like the distressed, grungy look, same with CAS.

Dream Home Decorator has some really good Build/Buy and CAS items but the career gets a bit redundant. I'm not sure if some of the bugs have been fixed.

My Wedding Stories hasn't been a huge headache for me but I've had some issues with it. I think that's mostly simulation lag though. In my current save, my sim just had a wedding and most of everything worked out. Tartosa is a really nice world. Build/Buy is nice. There are around 80 items. The CAS is nice and adds to the formal wear and party wear categories.

I, personally, haven't had a lot of game-breaking bugs with HSY. I've been mostly annoyed with the Social Bunny notification light on the phone, and the constant asking to be BFFs. Trendi and thr thrift shop are kind of fun. I don't like that prom is a weekly event and I wish it would have been an event we could plan (like birthday parties). Going to school gets a bit redundant but that's sort of like real life. I'm not overly crazy about CAS. There are only a few pieces I like but I'm old and very unfashionable in real life. As for BB, it's pretty nice. I do wish there were more swatches with the rugs but the beds' swatches are nice.

I'm not going to tell you which pack to choose but this is my opinion on the packs. Full disclaimer though, I play with mods. Before I even began playing with HSY, I downloaded mods to make it more enjoyable for myself. I use the Expanded Trendi mod and the More Classmates mod.

I'm with @DaniRose2143 here. Werewolves is a must have pack for me and I love it so much. Dream Home Decorator is okay, but I do kind of enjoy the career so it's something to consider. MWS is really bad in terms of micromanagement and things not working right. Personally I bought it for the world, but I can't recommend it as a whole. I have no real opinion of HSY as I don't own it, but I feel a bit negative about it.

I only have one of the packs mentioned but Dream Home Decorator is worth it providing you get on sale and just want it for the build/buy. The CAS items are nice but the career is buggy and not a good reason to buy it.
