Who is the last boxer to be better than Pacquiao?

[Manju]

"No one in recent history has done what Pacquaio is doing, which is tear through the weight classes crushing the best fighter in each division with an exciting style."

This--"crushing the best fighter in each division"--is not yet true of Welter and JrMW. Clearly, PBF and Mosley were the best WWs available, other than Pac himself, during his time spent in that division. For a while Williams was right behind them. Reasonable people can differ on who is to blame for Pac and PBF not yet fighting, but its fairly clear that Mosley and Williams were desperate for a Pac fight at welter.

I don't recall Margarito ever being listed as the "best fighter in" the JrMW division, so I don't see how PacMan can be credited with such an achievement. If he fought Williams or Sergio your point would hold though.

Beating Margo was a formidable achievement given the size difference....similar to what the Ruiz fight is to RJJs resume. But it would be an exaggeration to say Jones beat the best HW around. I mean, no one blames Jones for not fighting Lennox Lewis, and Pac should be given the same consideration, but such consideration shouldn't translate into him being considered the best in the very divisions where he's excused from fighting the biggest.
