What Ruy are we talking about, SF? Anyway Kenshiro should be superior to Goku and so would be SF Ryu but i don't who is better Ryu or Ken... (lol).
Anyway i am pretty sure that the victor is someone from the "Other" section.
Kenshiro is the best. He was said to master every kind of classic martial arts, has a DEM-level magic martial arts skill and capable of learning other "super martial arts" by seeing them just once.
He's pretty much "once you get in his range you're already dead" category.
