Mayweather's career vs pacquiao's career so far

Who do think has had a more impressive career so far? I looked at both their careers objectivly and here is what stood out to me. Before Manny moved up in weight to fight Oscar I think most people would say Floyd had the better career to that point. The biggest names on his resume up to that point were Oscar, Jose Louis Castillo, Diego Coralles, Zab Judah, and Gatti. Manny's biggest names were Marquez who is was 1-0-1 against, Morales who he was 2-1 against and Barerra. The reason floyds career up to that point is more impressive is because he was still undefeated having only been close to losing in the first Castillo fight. Manny had lost 3 times and had one draw. Both fought solid opponents up to that point. Since then Floyd KO'd an undefeated Hatton and dominated Marquez, both were comming off big solid wins. Manny beat the crap out of Oscar who had just lost to Floyd but beat Forbes in a warm up fight, killed Hatton who had lost to Floyd 18 months prior but had a solid win over Malignaggi, owned Cotto who had been KO'd my Margarito just before he narrowley defeated Clottey, and Clottey who just lost to Cotto. Manny looked better in his wins than Floyd did but if you look at the context of the fights and when they took place they are not that great. Manny should get a couple extra points for moving up so many weight classes so fast. Who do you guys think has had a better career?
