Who punched harder Lewis or Tyson?

[Taeth]

Earnie Shavers was the hardest of all time.

Shavers hit hard but a Prime Foreman hit harder than anyone ever in the game P4P...EVER

I so disagree... Foreman was more of a pummeler, he never really straight out ko'ed until Moorer, usually he would get an opponent up against the ropes and just pummel them onto the canvas.
