Not the 140 Ortiz, who was severly drained at the weight it appears (because he has trouble even making 147 now). And I don't agree that Maidana hits harder, I just think he was able to take Ortiz' punches better than Ortiz could take his.
I don't think Margarito had his bricks for that fight, he landed a ton on Williams and didn't rearrange his face like he did Cotto. That would be even more evidence that Margarito isn't that hard of a puncher.
