It'd probably not look as cool, at all. Since, you know, it'd be WAY more brute force and as little unnecessary skipping as possible. I watched some people show their stuff on... whatever that Discovery show was called. Ohyeah. Body, Mind and Kick-ass Moves.
Basically, if two hyper-mega-ninja like that would meet up on a street and face off, it'd either be over within 6 mind-blowing seconds of subtle blurryness, or they'd just shake hands go have a beer. A special ninja-beer.
One of the major tricks to ninjaness is knowing your opponent, though, and if they met each other for the first time, none of them could do any of those neat controlling trick things. So I think it'd be mostly super-offense, try to get the first hit. And once the first hit impacts, the other fighter either goes down, or manages to foresee the situation, blocks, and takes his opponent down.
In other words, other than really quick, it's not really all that exciting.
