Armstrong, he's too busy and better inside and he's one of the all time pound for pound greats. Chavez is a great fighter but Homicide Hank is a level above.
Julio Cesar Chavez was one of the greatest and I have all the respect in the universe for him. But Henry Armstrong was something never seen before and never will be again. A man who simultaneously held crowns in three weight classes. Chavez was truly special…. But Armstrong was the only one of his kind
Armstrong was near unstoppable in his 135 days, his biggest danger was losing multiple rounds to fouls. He beat good welterweights while 135 and below. I'd have to favor Hank but i'd hardly count out the chances of Chavez either. He was a beast at 135.
I don’t know how you’d make a case for Chávez. I mean, compare him to Duran - he’s clearly inferior & a level below that man, & most would even hesitate to pick Duran against Armstrong. It’s just a different class of legend.
