In relation to humor, speed of wit, sarcasm, on the point, association, political judgment, relation to topic, relation to interviewee, insight, good points etc etc
yes i know these are all from "that land". But they seem to be most prominent on the web.

I can relate more to stewart & colbert. Colbert is "overacting" whereas Stewart seems sincere. They seem to have more of goal in their interviews, outwiting the interviwee shows criticism but on one side seems to be their only goal. But atleast you can see minds churning.
the rest no comment.
