All packs have potential to be worth it depending how you play and how much of the pack you think you will use. I do recommend waiting for a sale though if possible because (IMO) no pack is worth the full price except a small select few.
1. Cottage Living: It's new and likely won't be on sale for a little while, however this is one that I would (and did) pay full price for and I have no regrets. The oversized crops and the animals add so much to my style of game play and the CAS is adorable. BB is lacking a bit but what is there is really well done and there are a ton of beautiful items in the debug.
2. Snowy Escape: I like building and I use this pack daily. Mt. Komorebi is beautiful but a lot can only be done in that world so the pack is game play limited in that way. Again, adorable CAS though.
3. City Living: Apartments are fun for a minute, comes with karaoke though which I use in almost every bar build now. CAS is pretty and the festivals add some extra flavour to the game play. I use the yard sale table constantly though and I couldn't imagine my game without it anymore for Rags to Riches style game play.
4. Get Together: Clubs are useful. That's about all, I don't use anything in this pack often and I'm glad that I waited for a sale for this.
5. Tiny Living: The BB and CAS are super cute. I needed to have that murphy bed. I do not regret paying full price for this, but now that it's a bit older, a sale price might be better. We have a lot of similar CAS in other packs now since the release of this one.
6. Discover University: I could have skipped this pack. Regret paying full price. The CAS and BB is great. University game play is a boring chore (IMO) and there's no replay value here (again my opinion). The boost that you get to the career and the time that it takes and the boring grind through just isn't it for me. The only reason this pack isn't dead last is because I do use the clothes, hair and BB almost daily.
7. Parenthood: I used the counters often but that's about it, and now that more packs have other counter options, I use them less. Some cute game play added with the pack but the messes the children make killed the pack for me. It's constant and you can't turn it off. Prepare for all of your community lots to be destroyed or to spend half the time that your sim is there just mopping up after the neighbourhood brats.
