Bumping this, since I've at last actually gotten around to watching one of these shows.

God damn! I love Azumanga Daioh so much. It is by far my all time favourite anime. It's uncomprehecible how much I actually like this show. It's gotten to the point where I am actually sad that I will never get to meet the girls in the show. The characters are so unique and deep thet they feel real in a way I have never experienced in another anime.
