I guess it depends on what you are looking for in a pack. For me I tend to lean towards family play and family activities, so Parenthood, Get Together, Outdoor Retreat, Kids Stuff were must haves for me. But I also like playing with single sims and exploring and experimenting with them so City Living, Get Together, Vampires and Get To Work were fun. I have different saves for different moods. In one save I have a single sim who I want to be a scientist and go exploring, in another save I have an evil vampire, I have a legacy save and I've also just created a simself save. So it really depends on your moods and playstyle :)
