Eccentric highschool boy and a normal girl that unwillingly gets dragged into his weird behaviors. Lots of comedy, but Yugami-kun has actual romance while Tonari no Seki is purely gag manga.
Both had solid foundations for a memorable story, and both failed to use their potential resulting in disappointingly bland animes.
Demon-lords adapting to a normal society, resulting in plenty of awkward (and funny) situations. Both shows constantly mix up comedy gags with more serious action scenes.
Similar absurd, sometimes surreal, type of humor focused on a group of unusual high-school students. The main difference is that the deliquent motive is the core of Cromartie comedy, while in Nichijou it's only a part of a very wide array of skits.
