I've never been sure what to make of Marciano, part of me thinks he's was over-rated but then another part of me thinks he was under-rated. I mean - He did destroy Joe Louis, yeah Louis was past his prime, but even an over the hill Joe Louis was still a helluva fighter and he was unbeaten and he did beat everyone in his era.
I think he was caught between two stools, to young to fight a prime Louis and retired before Liston and Ali.
Prime for Prime ? I'd have to go with Ali. I think from youtube clips I've seen of Rocky, he would have been to slow and a prime Ali, would stayed on the outside, winging and slashing punches at him and busting him up and maybe causing a cut stoppage. But if Marciano, were able to close the range and find his shots, or leap in and catch Ali then that could have been interesting.
But Ali had a cast iron jaw, so he would not have crumbled. Marciano didn't hit as hard as Foreman and from what I have seen of him, he did not have the bobbing head movement and speed of a Frazier. But this is all speculation. It's always hard to compare great fighters from different eras
