Lennox Lewis or Joe Louis

That left hook was epic. If he had Povetkins durability and dedication he would have been near unstoppable.

 

Louis is the better boxer and has the better resume. He made 25 title defenses a record for any division. In an era with only one belt. Lewis got picked off at 9 defenses and his first go around he didn't even have to fight for the belt because it was handed to him by bowe. He quickly lost it to McCall.

Who faced better competition is debatable. The men Lennox faced were much bigger and in that sense I think they would beat much of Louis's era fighters. However Joe Louis fought more prime top quality opponents and the fact some of these men had more losses is irrelevent the sport was much different. The amateur system wasn't as refined many of these fighters learned their craft as a pro and piled up losses early on. Today 0 losses is something to protect wasn't so back in Joe's time.

h2h Lewis likely wins he is good enough to win with his huge size and weight difference. If Joe gets modern training or supplements like Holyfield and comes in a ripped 225 he blazes Lewis .
