Like everything, there are pros and cons . I don’t think this is a serious attempt to say that this guy is better in any way than Floyd, it’s just pointing something out.
In the guys favour,
1. It’s a fantastic record
2. Massive kudos to be able to stay at this weight for so many fights. Manny starting a tad heavier than this and ended up at LMW. which brings me to the next point
3. Not a whiff of PEDs.
4. Good mental strength to be able to be in top shape physically and mentally every fight, no bad days at the office.
Cons
1. By virtue of it being the Minimumweight, there are way less competitors
2. This means repeat fights and some with lesser experience/debutants

So in summary, the guy should be given massive respect for what he’s done and it is a moot point making any comparisons.Apples and Oranges.
