Who's the best "pound for pound" out of these awesome all-time greats. Willie Pep Roberto Duran Henry Armstrong Joe Louis Muhammad Ali Harry Greb

Here is the order Bert Sugar has them in from his book, Boxing's Greatest Fighter: #2 Henry Armstrong #3 Willie Pep #4 Joe Louis #5 Harry Greb #7 Muhammad Ali #8 Roberto Duran (Robinson was #1 and Benny Leonard was #6).
