Do you give less credit to a boxer beating someone moving up in weight?

Sorry if the thread title don't make sense but I'll try to explain. So obviously there are a lot of great fights between 2 p4p rated fighters, and while there are catchweights, sometimes a p4p fighter will be moving up in weight for the first time to move up to fight another p4p. I just watched Salvador sanchez vs wilfredo gomez and what a classic fight. And while Gomez would later still defend his superbantam belt and would later become featherweight and lineal super featherweight world champ, he still had to climb up 1 weight class that he never fought at to fight Sanchez. Chavez did the same for whitaker (and there was a catchweight), Azumah also had to climb up to fight Whitaker, Mugabi and Duran climbed 1 up to fight Hagler. most people don't really mention Hagler beating Duran as a great win because Duran was naturally smaller and never fought at middleweight, despite Duran later winning a middleweight title six years later. I enjoy watching all of the fights I mentioned, but sometimes I wonder if they would've been better had these boxers were the same size. idk im just rambling. dunno if anybody else thought the same.
