Lighter person, all other things being equal, same height (or even the same person,) 25 lbs lighter, is going to be moving less mass _and_ he's going to have the lower coefficient of drag. So it's almost a moot question. The lighter person has it easier on both fronts.
But I still contend that being 17% lighter is going to make the task easier, far more than whatever difference in drag the two bodies have. Take a more extreme example: 5'8" 150 lb runner vs. 6'4" 175 lb runner. Lighter, average body type vs heavier, thin body. I'll contend again that the lighter guy has an easier time, whatever the wind resistance. I doubt that there's even much difference in the coefficient of drag between the two, and not enough to make much difference.
