Which character in smash up do you think is best and why?

I ask because I have no idea. I've been playing with Leonardo a lot and I seem to do okay with him, but I remember i was playing online with this one guy all for like two hours and the entire time he only used Michealangelo and he beat me all but once. Is he a better character or just a better player (this was my first or second day playing so maybe I've gotten better since then)? I know that with smash bros there are always only a small handful of characters that the "professionals" play with so I was wondering if smash-up has started to break down in a similar fashion where there are only certain characters the pros play, or if there are certain characters that are particularly unbalanced either as being too good or too bad.
I unfortunately can't test this for myself at the moment since I need my roommate to bring up his wii (at the time I was playing at my parents and my brother has a wii there), and even if I had the wii with me I'm not that good and I don't know if I'd be able to discern for myself which characters were good or bad.

My faves are Karai and Shredder. I dunno about the best but I like karai's overall speed and technique and all her moves. And Shredder, gotta love the Tengu Sword attacks.... as well as using the Cyber Shredder custom.

I think the best are Nightwatcher and Shredder.

They are both powerful but Shredder is more slower than any other character and Nightwatch has a lot of power and long-reach attacks.
