It's hard to tell. But, I do love three of them.
Jock is convenient because I can take photo with friend and school cheer is awesome and funny to watch! And they can throw several parties that not available when they didn't join jock before.
Rebel is nice because can add herb things that work like 'Kick up the notch' Natural Cook has. And my Sim can do Protest plus I can get extra skin for my smart phone. Show off Gizmo usually can make me laugh~
Nerd is something too. Well, I notice that being a Nerd my Sim can learn faster. Trivia Quiz is kinda funny. Mind Meld is useful to learn trait or stealing some information/gained friendship/gained skill point at random chance. There a several interaction that was funny to see.
