Chaos vs Sephiroth (one winged angel)

I bet someone has made this thread by now but still I wanted to put it out.
Sephiroth as he is in his one winged angel form which is the 2nd to last fight you have with him as well as the hardest. In the game he is able to destroy the entire solar system and blow up the soon (for some reason it doesn't kill cloud I mean WTF is up with that???) VS
Vincent Valentine in his chaos form with his best weapon (lol sorry forgot the name of it).

So ya'll tell me who would be the victor of this fight?

sorry about the typo ment sun not soon..

I think Chaos vincent would win

Er...Sephiroth for the win. It took the entire party to defeat him. Vincent alone will be nothing to One Winged Angel Sephiroth.
