Well I completely disagree but Wlad does have the superior record and ranks higher p4p historically because he has been so dominant for so long....
Byrd flat out said Vitali was harder to fight. Ask Peter, Sanders or Purrity who was the tougher of the two, and their answer will surely be Vitali. Vitali says Wlad is better. Wlad says Vitali is better. We will never know for sure, but a fantasy fight between the two comes down to this. Vitali has proven he could take Wlad shots. Wlad has not proven he can take many solid shots. Psychologically, I think Vitali would own a big edge over Wlad.
