IMO:
Both fighters have the frame to meet at any of these weightclasses in fighting condition. Typically it's harder for the fighter coming down in weight to maintain stamina for the fight and it's harder for the fighter going up to carry the weight. Mayweather's style kills Marquez in any class.

JMM 45/55 PBF @ 135

JMM 40/60 PBF @ 140

JMM 35/65 PBF @ 143-145 (Match/Weightclass)

JMM 30/70 PBF @ 147
