Writing about the ones I own:
Growing Together I held a grudge against this pack because it introduced the milestones bug that turned me away from my main save for half a year. Now the bug has been fixed and I'm willing to forgive everything because in fact I love this pack. Milestones, compatibility, family relations, trait discoveries and midlife crisis. Especially love midlife crisis, gives something extra for adults and can give their life a new direction. Kind of hate the world and haven't looked into CAS/BB closely, seems boring. Still recommended.
Horse Ranch I only got this pack the other day because of the bug mentioned earlier I witheld buying any content. But this is my dream pack. I have given two of my sims horses by now. I love the horses. I just watch them walk when my sims goes on a relaxed ride. I am into the world and the western theme, these would have been my choice. I admit it seems a little light content wise even at this point and I understand people calling it a game pack. I haven't really checked out the CAS/BB, but I have positive feels about it.
For Rent I truly cherish the option to have more than one families living on one lot. This is a game changer. However I'm not super interested in playing as a landlord. I tried it and it felt okayish. Tomarang world I love to the bits. It's smallish, but the size doesn't bother me much. BB is interesting. CAS I haven't closely looked into, but kinda like it?
Simtimates Collection
I bought this kit while I said I wouldn't buy any content. Oops. The underwear department in game is severely lacking and this kit fixes some of that. As someone who plays vanilla I like it! Simple kit for simple needs.
Modern Luxe
I don't really want to complain about free content, but anyway not super interesting.
