His most impressive KO has to be a toss up between Austin and Brock.
I think his best win is the first fight vs Sam Peter for the following reasons:
#1 At that time Wlad was believed to be "damaged goods" due to the shock losses to Sanders and Brewster and of course a poor showing vs Williamson.
#2 At that time Sam Peter was viewed as the next surefire Champion. Wlad was done or was about to be, Vitali had retired, and Sam Peter had just looked like a beast in the run up to this fight (that was the line of thinking at the time.
#3 It was the first fight where Wlad was put to the fire and came through the other side and since that fight he's had very little trouble in asserting his dominance.
Simply put the first Peter fight got this win streak rolling, it made Wlad a better more confident fighter, and he's been able to deal with adversity since then (like when Brock cut him, he went out and KO'd him because he knew he had to).
Chris Byrd was by far the best boxer Wlad has fought, but none of Wlad's other wins have meant as much to his career as the one vs Peter. That of course was also where Manny Steward proved his worth in the corner for the first time with Wlad as well. The Tony Thompson fight was pretty good as well. Tony is a good boxer, nobody wants to fight him.
