Is Floyds Resume One Of The Best Ever? Could you give me some insight, I'm not too familiar with it

When I judge a win of a fighter, I look at,what did his opponent go into and I look at his past 5 fights.
So here is what I gathered:

I am not talking about how many world champions he beat. Everyone is a champion today, I'm talking about who he beat.

Diego Coralles: Based on his record he seemed pretty overrated,I don't see that many names maybe besides Garcia. He reminds me of Wilder,who just beat a bunch of names and people hyped him up to beat Fury. Also I heard Floyd fought him at a catchweight.

De La Hoya: Who came off of a KO from a body punch by Hopkins and lost a decision Mosley

Castillo: Was a decent win actually. Props Floyd

Hatton: This arguably was a great win, he won Kosta Tzyu and Castillo. Props to Floyd

Marquez: This win is a bit underrated, yes he had a loss to Manny,but he did beat Barrera so decent win.

Cotto: After the first Margarito he was done. Also he was KO'ed by Manny,but I don't give Manny that much credit ofr that either.

Canelo: This is his best win in my book. Amazing.

Maidana: Lost a decision to a no name and lost to freaking Amir Khan.

Paquiao: Manny lost a decision to Bradley and was iced by Marquez.

Floyd was also past his prime in some of these fights,but the thing is a lot of these fighters like Manny style wise was so reliant on youth and they had higher risk fights and went into wars so there's that too.

if you compare this to say Leonard;

Duran: the 2nd and 3rd time was amazing wins. He fought Duran off of a career defining victory,he could quit for one reason or another,but he lost, that is like saying Mike didn't lose to Holyfield the second time. We could what if,but facts are facts, Duran was undefeated (Avenged his loss) at this point and I know he was the lightweight monster and went to Welterweight but still. He fought Duran the 3rd time off of a win against Barkley,Barkley had a deicison loss against some guy, but look who he beat before Duran beat him and you will forget it.

Hearns: Gave him his first L in a 14 round TKO.

Hagler: Hagler came off of his career defining wins in Hearns,Duran and Mugabi. (this is back and forth,depending who thinks who won,but still).

Benitez: if you wanna go there.

Someone please give me some insight on why Floyd's resume is so great, because I don't know his career enough

 

But from what I heard, he beat Coralles either at a catchweight or he was drained according to his trainer. Also, Coralles beating Floyd is the same mentality I had against people who beat Wilder, He knocked out everyone sure,but who did he really knock out? And when he was gonna knock someone out with a name, he himself got knocked out. Tyson Fury defeated Wladimir klitsckho after 10 years of being undefeated and off of wins off of Povetkin and Pulev which were ok to decent fighters at the time. So that is why I question that win

 

Also at the time Canelo was unproven, true. But he obviously was skilled, but I don't know who would have won if they fought later,probably Floyd though

 

I still hated the fact that Ali was dead set to fight Frazier the 3rd time. Or even Norton the 3rd time. I don't understand why he was so dead set on fighting people that were poison to him. Unless these guys were mandatory.

 

But the problem with Floyd,Aside from Hatton and Canelo. His fighters either came off of extreme loses like getting iced ala Paquiao or drained like Corralles
