Which Heavyweight Champion had the superior "Sleakly Sculpted" Physique. Evander Holyfield or Ken Norton?

Physique wise you would have to go a long way to find a better one than Frank Bruno, wasn't the greatest boxer although he did hold a world title at one point, his physique was absolutely amazing, the only thing is i would say it hampered him as all the work in the weights room made him bersome when fighting.
