The Joe Rogan discussion is what prompted this thread in the first place, as it came up at my work last night and the opinions where pretty much split. So I decided to bring the debate here for further analysis.
That being said, Rogan has displayed a long history of prejudice and bigotry toward gorillas, which is why I find his deductions dubious at best.
Team Gorilla all the way. Greater strength, agility, intelligence, and bite PSI. Though I should add that the fight should take place on neutral ground, something like the bottom of a swimming pool or a hard plastic cage like Magneto in X-Men 2.
