Bisping is OK. I respect him, he obviously has a strong personality and will power, but he seems like a bit of a dick sometimes. I liked a few of the Brits on the latest TUF, hopefully one of them develops into a top fighter.
I like Alves' style, but from what I've seen GSP is very good. Alves is apparently not so good on the ground, so I wouldn't be surprised to see GSP win that way.
