Favorite expansion pack?

I love so many of the packs but seasons comes in at first. It just such a great pack and it adds so much to the game. In second I would have to say cats and dogs. I love my little angels in real life so why not have them in the game. In third is city living. I just love the idea of living in the city. And fourth is get together. it is just not my favorite. And fifth is get to work. It just does not bring that much into the game. I almost feel like it go ripped off.
