I'd generally bet on the predator. He wiped out a special forces squad on his own, and he didn't simply rushed in the battles with massive plasma fire. He demonstrated patience and skills while hunting down Dutchs pals, so i consider him as a quite competent and experienced hunter. But we haven't seen the alien fighting a real threat (somone who is trained to fight and is armed with more than a self-made flamethrower), so i'm not sure about its real skills. The location of the battle would be important, too.
