You really think sitcoms work that better in animation than dramas? There's more animated sitcoms than animated dramas, I'll give you that, but that doesn't mean the medium is better suited for sitcoms. If the sitcoms are on the "cartoony" side of things (i.e. The Simpsons, Futurama, Family Guy), animation can be an advantage, but something like King of the Hill would be much better with live actors.
