Yeah, Calvin and Hobbes is vastly superior to Garfield, definitely. . . of all the ones on that list, Garfield is probably my least favorite. There's some sense of cockiness in Calvin and Hobbes, though. . . like, I can make intentionally unfunny comics sometimes and still get away with it (I mean touching rather than humorous. Always a waste of my time). It may have added some depth to the comic, but I imagine one could pull that off without completely eradicating the humor in a certain strip.
Calvin and Hobbes is excellent, though, don't get me wrong. That one little thing just annoys me sometimes.
