I'd give Bruno the clear nod.Bowe was by some way the better fighter though.If he had possessed Bruno's work ethic I think he would have been an all time top ten heavyweight.
Bruno was incredibly strong and powerful, but Bowe's offensive prowess comes from his relative speed and agility. He delivered his shots much more effectively.
. I have to disagree Bruno had legitimate top end power,but was too stiff to effectively land it often enough against the better men he faced.
