I've heard people say over and over that this era of HWs is garbage. Others have said it's only weak because Wlad and Vitali are so dominant. Well, here's my opinion on the matter:

The problem with this era is that we don't really know how good the non-Klitschko fighters are. Haye's best win after losing to Wlad was Chisora. We could have seen how good he is by fighting Fury, but that never happened.

Thompson's best wins are over glass-jawed Price and Solis, who is a prime example of wasted potential.

Povetkin went life and death with Marco Huck, a CW, before fighting Wlad. His best win is Charr, who is extremely limited.

Wilder is still unproven, and there are still some questions about Fury. Fury has fought better opposition, but he didn't exactly look great against Chisora, Abell, and Cunningham. His upcoming rematch with Chisora should tell us more.

Stiverne has two wins over Arreola, but other than that, his resume is poor. No matter whether he or Wilder wins in their fight, they're both unproven.
