Very good question Xplosive. I'd give Nelson the edge by a whisker. Beat better opposition IMO and won in titles in different weight classes during a period when that was a very difficult thing to do. Cervantes did brilliantly for someone who used to sell counterfeit cigarettes to survive childhood
Nelson by a distance for me. Incredible longevity and championship run. I tend to think of Cervantes as a bit of weak mechanical titleholder
