I think Holyfield wins a UD, no question. Joe did best against rangy boxers or guys that were straight up and down. Holyfield was neither. He used angles, could strand and trade with anyone and usually get the best of it, he had speed to match Joe, and he could make adjustments a little better imo. The peek a boo stance doesnt work well with a hustling boxer puncher like Holyfield. His 3-4 punch combos in close, primarily the uppercut, win Holy the fight. Joe would roll into a lot of punishment.
