Who had the bigger punch? Tommy Morrison or Frank Bruno

It has to be close, Bruno also hit like hell.
Morrison for better single punch. But would it be as hard without the PEDs?

 

Bruno was a heavier puncher but Morrison had more one-punch KO potential in his shots.

 

I'm not so sure he did. Comparable resumes imo

 

I think it’s difficult to fully ascertain who hit harder. I think they BOTH punched pretty hard, but I don’t think either of them KO’d too many guys who were known for their durability. Both retired with impressive KO percentages though.
