What Are Your Favorite and Least Favorite Sims 3 Expansions Packs?

I absolutely love Showtime and Late Night. I'm a sucker for color, neon and 1950s memorabilia (I adore jukeboxes), so that can explain it. There's also something about the objects where I'm using them in 90% of everything that I build unless it's old-fashioned. They're incredibly flexible.
