It looks like you have answered your own question with accomplishments. Pacquiao is still semi active. I don't get why so many want to compare Mayweather's career with Pacquiao's career. They have completely different backgrounds. Pacquiao and Duran have more similar backgrounds both coming from living and working the streets. Mayweather is from a boxing family and had a prominent armature career before turning pro. I think a better comparison is with Dela Hoya.
