I say Family Guy its more original since it has hilarious flashbacks and other references. So if its a new episode then you cant really know whats going to happen since its basically a totalyl random show. South Park on the other hand isnt bad but its very repetitive the characters just dont evolve for example Cartman and Kyle do the same things in like every episode. While atleast in Family Guy the characters evolve a bit like stewie who started out wanting to kill lois and now he rarely even mentions that if at all.
Also ATHF and Shin Chan are awesome along with Super Jail and Venture Brothers.
