I can see where the Simpsons and Griffins are the same, but look at them compaired with other sitcoms as well. Peter and Homer are morons, most husbands on sitcoms are. Their wives are intelligent and almost always right, so are most wives on other shows. The Simpsons and Family Guy are like lots of other sitcoms as well.
I like Family Guy better, slightly, because of the non sequitors, though I've noticed The Simpsons seems to do a lot of them now too. When FG isn't trying to be overly political, it's pretty funny.
