{Poll added] Name an animated series that rivals Steins:Gate or Rick & Morty?

[Mnementh]

Well, these three are very, very different. You put wittiness as combining feature? Well, I don't really see it, as still even the wittiness is very different in the three.

Nevertheless: Futurama, Yona of the Dawn, Mushi-shi, South Park are very good animated series.
