Absorbing Man.
I think AMAZO has the better powers, but I tend to like human/alien characters over straight-up automatons, even if they have personality. Plus AMAZO's comic "costume" is one of the worst ever. Not that Creel's that much better, always dressed as if to say "yeah, I'm already ready to be thrown behind bars", but at least he doesn't look like he's attending both a St. Patty Days parade and a Gay Pride parade at the exact same time...
