Which one would you rather be? I'll assume that most everyone knows the different powers, looks, etc about both. Even someone who knows just the basics of them can answer this question. I'd want to be a sith. They just seem so much more fun xP
anyway i would go sith not because of looks but because what they stand for learning the force though emotion instead of discepline but i'd probally mix the 2 after all practice makes perfect
Btw, the jedi church really has nothing to do with Jedi. They just use the language of Star Wars to describe what they believe. (I had too much time on my hands one day....)
