Vitaly almost beat lewis last time. From what I remember he was actually winning but had that cut on his eye that forced him to stop.
Wlad was the one years ago when he was 25 that most predicted to the next great heavyweight, but vitaly has been the force of the two up until recently. I think wlad's day has come to be the best fighter in the world. Hard to count out vitaly though, so tall and long and deadly accurate... just doesn't have that knock out power Lewis had.
