I voted 16-25. I think he falls just short of the very best men i.e. Ali, Foreman, Frazier, Louis, Lennox, Holmes and Evander. But them guys all have the advantage of Hindsight and we all see things rosier in the past.

Also the guys above had better rivals than Wlad. But to be honest I do think he would fall short of the very best, it's a shame he'll probably never fight another great HW.
