Honestly, looking at the end of the episode, I'd say Tweek. Tweek was able to beat up Ned, a Vietnam veteran to the point that he coughed up blood (though Ned was missing an arm and Tweek did have to hit him in the balls first) whereas Craig was not only defeated but KNOCKED OUT by Cartman of all people, someone who was easily beaten up by Wendy and Kyle in later episodes. Additionally, when both of hospitalised, Tweek only has a few bruises on him, whereas one of Craig's eyes had swollen to the point of shutting. Though I'd say Tweek, it is possible that they fought to a standstill.
