I personally like The Simpsons better, partly because it's cleaner, as far as sexual content, and the fact that I just like the style of humor on The Simpsons more.
it has gota be the simpson is it a legans and very wel known other the owrld and personly i think family guy is kinda a copy if you no what i mean of the simpsons
simpsons has the history, and is pretty funny. family guy is halarious because it has raw humor, unlike simpsons that dulls it down a little. I've been watching simpsons longer, but im gunna have to go with family guy
