I think they are both coming along nicely.

Lopez has beaten enough top fighters to be top 5 p4p imo. Donaire beat Vic and goes as high as number 4 p4p.

Lopez has beaten Ponce, Penalosa, Leuvano and Rafael Marquez, that's a hell of a resume for someone still on the up.

Gamboa has only had 19 fights and is already holds the WBA and IBF superfeatherweight titles. Sure he's not beaten anyone to get them but being a double world champ inside 20 fighs is hardly being moved along slowly.

Besides, technically he has things to work on and so shouldn't be rushed. He has the belts, which means he'll be on a nice little earner every time he fights, he can afford to give himself another year before he fights the best in the world imo.
