I thought there'd be some interesting replies in here. I should've included one more option in the poll, being Undetermined, but that hasn't stopped the great replies so far~
Lol, I also thought about this topic from Cell, so it's funny you mention that.
I also think stamina would indeed play a huge role here; the first one to tire out would probably be the one to lose. But if we were to assume both could last relatively the same amount of time and pretty long, I'd say it'd end in a stalemate myself. If both are skilled fighters, able to learn their opponent as they fight, then perhaps they'd both be able to find a weakness in each other's tactics to land a decisive blow. But the other wouldn't willingly let that happen either, so they'd be put on the defensive the moment the other goes on the offensive.
