That doesn't change the fact that one fighter is superior to the other though. You can't just bring both fighters to a level because one is a few years older than the other. Boxing doesnt work like that.
Of course the Wlad win loses some credit because of his age, but nowhere near enough credit to mean that he is now only on the level of Ortiz. Wlad dominated the division for years, Ortiz best win is Bryant Jennings. He didn't exactly look great before the Wilder fight either, did you see his fight with Dave Allen, a British journeyman?
Wlad turned up against Joshua, looked great physically and showed his class, Ortiz looked like he was feeling his age more than Wlad. There's no debate here, Joshuas win is clearly superior. If Wilder was the one who had beaten Wlad then his win would be superior, but he hasn't done that.
Mind you, it seems like PUO3 is the only one who can't admit that.
