Who is Greater between Holmes or Marciano?

Larry Holmes is better IMO. Better longevity, better skills and bigger guy. No real weakness to speak about.

I rank Holmes #3 on my all-time list behind Ali and Louis and I have Marciano somewhere between 7 and 9 in my rankings.

I feel that Holmes fares better head-to-head against other great HW's but a Marciano-Holmes fight is a tossup.. Holmes wins 6 out of 10.
