I do not have the two newest ones, but I do have the others, so here are my two cents:
Horse ranch: If you like cottage living I can't see how you cannot love horse ranch. Raising and breeding horses is fun, the gameplay attached interesting and I personally have enjoyed the horses immensely. It's also easily combinable with farm work, although the nectar making is a bit repetitive, especially as it only gives one bottle each time (there is a mod for that though). Chestnut Ridge is beautiful, but the town centre somewhat lacking with lots of empty spaces and shells. A bonus for the shops in town though, even if they are rabbit holes. I find the BB extremely useful for the rustic farmhouse look and also for historical gameplay. On the downside, with rotational play the horses won't develop while you are playing the other families, and if you combine a farm with a rental (say you rent a room at a farm, or want two families to share a house) then the horses will only show up if you're playing the family that owns them.
For Rent: I have personally enjoyed this a lot and played it A LOT. I like the apartments, the way you can make a town more alive because more people can live on the same number of lots. I really enjoyed living in an apartment or having family members live "next door" and the game play for owning apartments are as immersive as you want it to be but you can also mostly ignore it if you just have a high standard enough and turn off events. The one bug I experienced is the fire-bug where a family will be cursed and the fire bug stays. It took a lot of effort to make it go away and for a while the game was almost unplayable, but you can get rid of it, and if you have rental events turned off it won't appear. The BB is extremely useful, and I use it a lot for everything. The major downside for me is the world, which is beautiful but boring, useless and with nothing much to explore other than empty space, useless shell buildings and rabbit holes. Also the new kids games are great. I use them in every world, especially in parks and kids will gather and play.
Book nook: One of the best kits. I use the shelves for everything all the time. I have nothing negative to say, it's brilliant.
Chrystal creations: I haven't played the actually jewelry making part yet, as I bought it for bb and cas, but I do like both those aspects. Will try the game play when it fits into my story.
Bust the dust: I like being able to vacuum but the system seemed a bit aggressive to me in how fast dust builds up. It's also impossible to vacuum in rooms with lots of furniture, the sim will walk outside to do it. I've gotten a few mods that tones it down and now I like it, but without the mods I couldn't recommend it.
Moschino Stuff: Meh. I like taking photos, but I often forget, so yeah, maybe. Not my favourite pack. BB and CAS both rather useless. But you can take better photos of people with it.
