Pound for pound just based on records Hatton, but in an actual fight Margarito. I hate Margarito with a passion but Hatton has 0 business of ever being int he same ring with Margarito. Hatton could barely take Collazo's punches, Margarito would murder Hatton.......yes seriously murder him, I'm being quite literal here.

In a battle of pressure fighter vs pressure fighter usually the bigger more durable fighter wins.
