Both are moe anime that are funny. Both characters are really cute and the characters have a wide variety of personalities, from the crazy/insane Ritsu/Mitsuba, to the silent/moe Mio/Hitoha. There are other teachers involved in the craziness, especially Yabe/Sawako.
BEWARE: Mitsudomoe is MUCH, MUCH stranger than K-ON.
