Armstrong alltime, for his career. H2H hard to seperate them. I lean with Duran but thats because Ive seen a ton more film of him and he was one of my favourites. Hank is always my no1 ranked alltime though.
Armstrong is in my Tier one equalling a ranking between 1 and 4 while Duran is on my Tier 2 equaling a ranking between 5 and 7.
Duran is simply better than Armstrong skill wise, talent wise and technically. Armstrong may have a better workrate but I'm nto sure about that. Head to head Duran comprehensively takes Armstrong apart it could well be 1sided Legacy wise Duran too, they both started at featherweight, where Duran had his first great win. Both were best at the lightweight limit and went all the way up to middleweight. Duran beat the better fighters with the greater scalps at lightweight, welterweight and middleweight So most will say Armstrong but they're wrong
We have to consider the subjectivity here, people on this board give so much credit to guys doing well against naturally larger men, and achievements across the weight classes. Armstrong is a great example of this, and Duran also, though Armstrong you could say more successful and consistent against naturally larger men, Duran has that doing tremendously well when well past his own prime, that similar thing enhances Foreman's legacy imo, and rightly so. Duran's is even more remarkable than Foreman's possibly in that sense. I cnsider Duran and Armstrong both absolutely prolific of the highest order in their own different ways, in a h2h matchup i take Duran. Well there you go, all ive done is sang both fighters' praises and come to no conclusion! Those of you who know me well will know i dont like p4p greatness debates, though im fond of weight division greatness ones!
H2H I favor Duran in an excellent fight, but Duran could simply do more. All-time P4P based on legacy their close, usually give the edge to Armstrong but At times I put Duran a spot above him.
