Obviously, the Abominable Snowman would crush them both. In all seriousness, I put my greenbacks on Sasquatch since he has had to fend off grizzly bears and mountain lions in the North American wilds while Yeti, the Himalayan hominid, must only deal with yaks and the occasional drunk sherpa.

I'm with Elfman on this one. Sasquatch occupies a tougher ecological niche. Also the fact that he's permanently out of focus will confuse the sharp-eyed yeti.
