Some people would probably disagree with you, which is just a matter of taste. On a whole, I find South Park funnier simply because it's less restrained. It's dirtier, cruder, and more offensive, so it can give a different type of laugh. Hope that helps.
nah I find family guy better, I don't mind some of the offensive jokes, but I think south park take it too far
Today's family guy is terrible. 2002-2006 were it's best years.
I like South Park because it reminds me of when I was a kid.
Let's be honest, family guy just ******* sucks balls.
