Hmmm if I had to list the ones that stand out...

Chris Byrd 1 - avenged Vitali's defeat, completely dominated/beat up one of the slickest and most underrated HW's of the 90s/early 2000s.

Samuel Peter 1 - Took on the scariest guy in boxing at the time, undefeated, brutal puncher, the guy who was supposed to "save" the HW division. Wlad was fresh on the comeback trail and still looked at as a huge bust with a glass jaw. Gutted through some tough spots and got the job done.

Calvin Brock - The name doesn't mean much anymore but at the time he was looked at as the next possible great American HW, an elite boxer who could punch. Klitschko ends all that hype with a brutal KO.

Ray Austin - Austin was not a great HW by any stretch but was world class at least, Klitschko destroys him in 2 rounds with one hand.

David Haye - Boring fight but I blame that more on Haye. After all the build up, Wlad completely nullified Haye's speed and power, he was aggressive, met Haye head on and was constantly moving forward. Totally outclassed his biggest rival/threat to the point where nobody was asking for a rematch.

Pulev - another solid undefeated HW, Wlad battered him around and ended with a brutal knockout
