I'm having the same dilemma as you in that I can't decide what team I want to start playing with. I'd vote for the Clippers though, as I'm considering them and they're pretty fun to play with. You have Brand inside for a veteran, and Cassell/Mobley/Maggette make a good guard combo (not to mention that Shaun Livingston is very fun to play with, especially coming off the bench and sparking some fast break points).
Edit: Forgot to mention that I don't think the Nets are a bad option either.
