What is your favorite Expansion?

Definitely City Living, it added so much to my game. I love the apartments (I much prefer them to the penthouses in the Sims 3) and I use them for nearly all my YA sims. I also love the festivals and the new gameplay in general.

Cats and Dogs is a close second. I'm not sure which I prefer between Get to Work and Get Together - I love Windenburg and the clothes that came with GT, but I also liked having aliens back and active careers with GTW. I never use the clubs system in GT though.

I'm all about cities and apartments so yeah! I like cats and dogs a lot too because of the furniture and well... the pets, but City Living furniture and San Myshuno overall wins

Wow! Thanks everyone! You have helped loads!

Get Together for sure! Initially when they announced the expansion I was super disappointed and didn't really know what it was about but it turned out to be the most pleasant surprise. Windenburg is so beautiful and full of charm and there's variety in each of the neighborhoods - I often try to move my sims elsewhere but always end up moving them back to live in Windenburg. Also a lot of the game play and items that came with it I use all the time.
It's hard to say which expansion would come up as my second favorite as they all have some stuff I like and some I really never use so... Still waiting for a possible seasons expansion to blow me away I guess :D

I love cats and dogs, well because I love cats and dogs. But the city living and get to work expansions are definitely two of the expansions I feel has had a lot to add. I love the idea of going to work with my sims. I had asked my boyfriend to pick a job for my sim, he picked the law enforcement career. I have been enjoying trying to look for clues to get her promotion. Really good stuff.

Get Together is the winner for me. It brought something new and super useful like clubs and the most beautiful world to date for this game.
EPs have been dissapointing so far, some more than others but none has really wowed me, not even the one I voted for.

It was a difficult choice as I was stuck between City Living and Get Together. With Get Together I love the new world, I use it in pretty much every save, but I didn't use the clubs feature enough for it to be the winner. In City Living, I love the festivals and the apartments. Therefore, City Living was my winner.

I was dithering between Cats & Dogs and Get Together, but the world of WIndenberg just about edged it. It's the neighbourhood I use the most.

I like the other two packs, but I haven't really done the playable careers in a while, and I found City Living to fall a little short of my expectations.

Personally I think all the EPs have something cool to offer, but Cats & Dogs suits my style the most.

I'd rank them as:
1. Cats & Dogs
2. Get to Work
3. Get Together
4. City Living

GT is really fun for the first few weeks but later on the club is just really forgettable since my sim will just get married and have children so there is no time for clubs and hanging out with friends.
GTW is really amazing with the active careers but just like GT, when my sim started a family and I have more sims to control and take care of so the active career just turn into a normal one for me since I never really join them.
Cat & Dog one of my favorite and the world is Amazing but the dog and cat get kinda annoying since they are always in need of attention which my sim could not give them cause of work and stuff so the pet are just like a member that just run around the house and help my sim to lose money faster.
CL is my favorite because of the 3 new careers that I really enjoy and the Work From Home feature that make it more realistic and the apartments feature is nice since I prefer to do the interior rather than the exterior which I suck at so apartment is perfect for me but to be honest, the neighbor is really annoying.
