They have contradicted each other on two occasions that I can think of; the existence of Primus in Omniverse (which we've already gone over) and the origins of Undertown. They've both said different things about them. Matt is more reliable than Derrick given that he was a writer (thus, he had more of a say over the story side of things) and Derrick had a tendency of replying to questions with jokes. The wiki considers Derrick's word as canon unless it contradicts comments from more important crew members or the show itself. Derrick's word contradicts both of those things, as well as logic. Like I've said before, there's not much of a use in arguing anymore, as neither side is going to convince the other that they're right.
