Favorite expansion pack?

I had to sit here for a minute and really think it through, but my favorite would have to be Get Together! As insanely lovely as Seasons is, I don't think I would enjoy my game nearly as much without Get Together, even if I had Seasons! I love all of the social aspects and the dancing and the clubs. Also Windenburg (is that the world?? ohdear) is ADORABLE. The feel of it is just too cute and makes it the perfect place for my simple sims who want to live in a little cottage. I also heavily utilize the club feature, seeing as I play with a lot of teens and it's really good for making groups or cliques or whatever I want. So Get Together is the one for me. ^U^
