Best stuff pack so far?

I choose Backyard stuff, I use it quite a lot, and I really like it. I was wondering on Movie Hangout, also for general feeling. However, when I think about it deeper, I think Kid's Room brought probably the most into the game, in my opinion. It really added the quality to kids' life stage, so for family players it's perfect, but it also brings something interesting for others - just some reason to try new things.
