Xbox 360 vs PS3. Which is better?

I would like to resolve this stupid argument. It's really like comparing oranges and apples. But say you had the money for one or the other, and you had to choose. Which one would you go for? I've heard great arguments and some really pathetic ones. I really want some straight up legit answers this time. No riff raff.
