My favourite is always Pets. The supernatural one annoyed me more than anything else, because having people with wings walking around and zombies moaning in your garden every night was just a bit weird. My second favourite would be Seasons (because it's so pretty!).
Pets are my definite favorite, along with Seasons, but my opinion is biased because those are the only expansions I have I’ve always wanted to try out Generations and University though.
It’s so cool to see what everyone else prefers!! I’m basic so the only expansion pack I have is Late Night, but thank you all for commenting your favourites!!
Btw just putting this out there, not for sims 3, but origin is having a sale for a lot of sims 4 content rn
