Who are the top 5 punchers in the sport?

Do you mean who punches harder or who's better at knocking out his opponents?

I come very close to agreeing with your list 100% but not quite. My list is 1 Joshua 2 Golovkin in a tie with Joshua for 1st place. 3 Kovalev 4 Beterbiev 5 Stevenson 6 Spence. I rank Beterbiev higher than Stevenson because he has terrific power in both hands. Stevenson has a great left hand. His right is powerful but not exceptionally powerful. Wilder and Ortiz are both big punchers but fall just short of making my top 10 hardest puncher list. I admit I'm probably ranking Beterbiev lower because he only has ten pro fights. He's the goods though. The Campillo and Cloud fights were impressive. I think Beterbiev could very well be in the midst of an impressive KO run.

1. Artur Beterbiev 2. Lucas Matthysse 3. Sergey Kovalev 4. Luis Ortiz 5. Guillermo Rigondeaux Honorable mentions Golovkin Stevenson Miura Briedis Garcia

GGG Kovalev Wilder Beterbiev Joshua

Ask Amir Khan who hits the hardest Lets hope for Amir's livelyhood he never goes anywhere near anyone on this list :fingersx:

Kovalev Golovkin Stevenson Ortiz Joshua

Khan Malignaggi Mayweather Lara Rigondeaux Seriously, though Golovkin Kovalev Wilder Ortiz Beterbiev

I think Beterbiev has a chance at proving top 5. I think Usyk is still another big question mark.

In all of boxing who is on your top 5 punchers list? I mean in terms of being able to KO their respective competition. Obviously a HW hits harder than a MW but if the MW is more likely to KO his opposition I'd rank him higher. If I had to rank them my list would go something like this: 1. Anthony Joshua 2. Gennady Golovkin 3. Sergey Kovalev 4. Luis Ortiz 5. Adonis Stevenson Honorable mentions: Errol Spence, Artur Beterbiev, Deontay WilderI come very close to agreeing with your list 100% but not quite.

Golovkin Kovolev Stevenson Walters Ortiz

Gennady Golovkin Sergey Kovalev Adonis Stevenson Mairis Breidis Anthony Joshua AJ would be higher ranked but I believe the guys above him have KOed people of a higher level plus most people AJ has stopped have been guys that you'd expect him to or people already stopped before. Breidis power is not properly recognised thanks to people not knowing much about the Cruiserweight division this guy is heavy handed and has a lot of good technique https://media.giphy.com/media/ZzspLw7AsiUnu/giphy.gif
