Easily Marquez. Marquez has faced the real compitetion as of late and he's facing Mayweather who isn't a shot weight drain fighter.
Pacquiao such a great person(very down to earth, he also help the poor people in his country) and great for the sports of boxing.
My man, the Pac who I consider among other things, the most exciting fighter to watch. Never a dull moment when he's in the ring.
