I'm not saying that a griz wouldn't prevail. But, I think you guys are grossly underestimating the gorilla. Those things are crazy strong and badass when pissed off. It would at least be a fight for awhile. A chimp v. a gorilla? lol Remember, we are talking one on one here, not a group versus one. And I personally wouldn't fight any of them unless I was trying suicide by animal.
