Better right hand puncher: Alexis Arguello or Thomas Hearns

I Love Louis, and he gets quite a bit of prestige, and perhaps, some exaggeration because he fought at the premier weight class for boxing.
The heavyweight division.
I can say one thing for certain, Hearns and Arguello's right hand prowess was showcased against much better competition, and over multiple weight classes.
Is any of Louis's ko's more impressive than Hearn's one punch stoppage of Duràn or Shuler? Or Arguello's over Mancini or Olivares?
Especially when considering the skill levels of those opponents?
The vast majority of Louis's opponents were not much better than Kevin Rooney, skill wise and we saw what Arguello's right hand did to him, and that skill level.
Louis was a technical marvel, and the greatest offensive heavyweight in history, with Tyson being a very close second .
But the heavyweight division has always gotten the fan fare, and media love.
Before UFC , heavyweight boxer 's were seen as the most dangerous men on the planet, with the ability to " Lick any S.O.B in the house". ( Thank you J.Dempey)
However they never were the most skilled....
Who had the best right hand between Hearns and Arguello?
Hell if I know, pick one..... You won't be wrong.

 

Thomas Hearns for me
