Favorite expansion pack?

Honestly it's a bit of a hard choice for me, having seasons in the game is great but while playing it, it just dawned on me that I just got excited about the weather which I experience in real for free! lol! I chose City living because I love the city and I love apartments and because TS4 isn't an open world you can meet so much townies just by them being your neighbor, meeting them at festivals etc. and when I think of starting off a lot of my stories it's always in an apartment because it's just more realistic that way! Not many people own a home right away and honestly seasons just didn't add THAT much for me, the holidays can be a bit annoying and sometimes the weather forces you to stay indoors when you want to go out. City living added new careers, apartments in a new world, festivals, great build/buy mode items and some nice CAS items too! a close second for me would probably be Cats and Dogs, I love Brindleton Bay! and the animals are cute most of the times but I tend to enjoy packs that create new things for me to do and a new world to explore, new townies to meet etc. but that may change who knows, but I pretty much love all of the packs that added new things to do!
