Here's my impression fighter by fighter. And this is totally off the top of my head, with little or no new research involved:
John L. Sullivan- 2 (hard to say how good his opponents were in general and he failed to stop all of the accomplished ones)
Jim Corbett- 1
Bob Fitzsimmons- 4
Jim Jeffries- 7
Marvin Hart- 1 (never stopped any body good over 175 lbs, and even Root was a late stoppage)
Tommy Burns- 1
Jack Johnson- 7
Jess Willard- 5 (a fair number of stoppages against decent opposition, but many were of the relatively late-round variety)
Jack Dempsey- 10
Gene Tunney- 3 (not as bad at stopping opponents as I thought, but probably due to skill more than raw power)
Max Schmeling- 4 (seems to have added power as his career went on but Louis KO aside, he wasn't an ATG puncher)
Jack Sharkey- 3 (lots of decisions, but a few early KOs against quality fighters, too)
Primo Carnera- 5
Max Baer- 5 (not really that devastating a knockout record against top opposition)
Jim Braddock- 1
Joe Louis- 10
Ezzard Charles- 3 (at heavyweight, mind you)
Joe Walcott- 3 (went on a tear of knockouts for his title win and right before, but mostly won decisions over the course of his career against high-level opposition)
Rocky Marciano- 10
Floyd Patterson- 6 (power probably underrated due to how easily Liston walked over him- lots of mid-round stoppages of good fighters in prime)
Ingemar Johansson- 8
Sonny Liston- 10
Muhammad Ali- 4 (rarely flashed 1-punch power, due in part to his style)
Joe Frazier- 10 (I kinda feel like his one-punch power may be a little overrated, but I can't bring myself to give him a 9)
George Foreman- 10
Leon Spinks- 2 (best guy he ever stopped was Bernardo Mercado)
Larry Holmes- 4 (decent number of stoppages, but mostly late and on accumulation)
Michael Spinks- 3 (hard to quantify. He stopped two solid fighters, but failed to stop the two very good fighters he fought in his relatively short heavyweight career).
Mike Tyson- 10
Buster Douglas- 3 (Tyson was his only KO against top-10 opposition)
Evander Holyfield- 8
Riddick Bowe- 10
Michael Moorer- 2 (never knocked out a clear top 10 opponent)
Shannon Briggs (

)- 2 (probably too big not to have more power than this, but the only decent opponent he stopped was Liakhovich)
Lennox Lewis- 9 (very underrated puncher. Got lots of leverage and flattened all the big names he fought except Holyfield and Tua, who had all-time great chins)
Hasim Rahman- 3 (gets some credit for icing Lewis, but had Lewis' momentum helping him and his overall KO record isn't that great)
Vitali Klitschko- 9
Wladimir Klitschko- 9 (both he and his brother are giant guys with telephone-pole right hands and really good KO percentages)
