The gorilla will have superior reach advantage. Its a toss up between those two I think. Theres a bunch of web sites out there dedicated to this arguement.
As far as the other animals......There are a few pics out there floating around that could decide for them. I've seen a set where a horse killed a mountain lion. Kicked it and stomped it to death. Picked it up with his teeth and threw it around some.
I've also seen a series of pics where this lion had killed a pretty good size alligator.
And this pic I have attached Iam sure some of you'll have seen. Its a anaconda that killed an alligator, or so it thought. It swallowed it, and with one last burst of energy the alligator thrashed will inside and split the snake open.
