Cloud, I think. It could go both ways, really, just saying...

I'd defiantly say cloud besided the fact that hes killed sephiroth multiple times as well as destroyed Bahamut sin..ect in advent children he was blocking bullets non stop during most of the fights and he swings that massive sword ungodly fast and he got shot in the head in advent children and only had a bloody mark on his head as well as surviving the shot to the chest at the end(though he did almost die there). As cool as vincent cloud has got the uper hand in pretty much every aspect of the fight.

Vincent will surely win against Cloud, In the Gold Saucer, where you canget cloud's final limit break wherein you have to fight lots of enemies and survive and collect pointsin order to obtain omnislash, i used Vincent and won easily, while when i used cloud, he never reached the last monster... Vincent's speed and shape-shifting powers will surely confuse cloud and finally beat his ass out! don't forget Cerberus! speed shooting!

why are some people here saying that cloud defeated this and that, remember he didn't defeat everything by himself, it is always a party or a team...

After playing DoC, I believe Vincent is the strongest life form on that planet. I mean, JESUS. He made Cloud look like a puss.

I would say that vincent and cloud are pretty well even on strength. Vincent is faster but cloud does have the omnislash!

My favorit is vincent
