Off the top of my head.. 1) Wilder 2) Joshua 3) Miller 4) GGG 5) Rungvisai 6) Stevenson 7) Inoue 8) Beterbiev 9) Lemieux 10) Joyce Honourable mention: Gassiev, Uzcategei, Kudryashov, Derevyanchenko, Ortiz, Garcia, Berchelt, Charlo (Note: this is by no means a perfect or complete list, with the order based on my own percieved level of notoriety each boxer on my list has currently achieved with regards to being a formidable puncher. Please bare this in mind before tearing me a new one.)
Admittedly I've only been into a boxing for a year and although I spend all day watching boxing and learning as much about the sport and the history of the sport as I possibly can during the free time I have, I am currently a n00b by all accounts and I guess you could call me a casual, therefore I don't take any offense at my list proving lulzy to those more knowledgable than myself, as any criticism, regardless of whether it comes by way of constructive advise or otherwise, helps me out. Therefore your point is appreciated and duly noted for future reference.
I put them in there based on their notoriety and popularity in the other boxing circles I participate in, taking into consideration their KO percentage more so than their power (as even I know that a HW is generally going to possess more power than the lower weight classes.) All the same, I'm not familiar with some of the other names which have been put forward in this thread and most of the names in my top 10 are undoubtedly interchangable with these other names. Nonetheless, I have admitted my list is far from perfect but all the same I enjoyed putting it together. It's nice to see some names I'm not as familiar with being mentioned in this thread so I can now watch their fights, research their records and then eventually ammend my own list accordingly.
No problem mate, i didn't want to say your list is garbage but i think putting HWs on the list is not making sense at all especially putting 4/10 from the HWD. Apart from that i think Miller and Joyce are not the guys who are having the hardest single punch KO power. Rungvisai, Stevenson, Inoue are good Top 10 calls btw.
I would also put Carlos Canizales, Kerman Lejarraga, Jaime Munguia, Callum Smith in my Top 10/15 P4P punchers. I already mentioned Angel Acosta who definitely deserves a Top 10 ranking. Srisaket Sor Rungvisai, Naoya Inoue should be Top 5 imo.
