South parks tears everyone apart and is completely irreverant. I like that. To me that's true comedy, fully uncensored and doesn't avoid making fun of certain topics, people for fear of being offensive.
Also their jokes tend to be on the money and pretty smart. Some episodes are even thought provoking.
I used to love both, but now not so much. I would have never been able to to decide which I liked more a few years back. Now I can't decide which I dislike less. It's like asking which testicle you would rather be kicked in; Either way it's gonna hurt XD
family guy. not that I don't like south park but it seems that today's south park is not as funny and entertaining as it was back in the early 90s and most of the episodes are practically the same. unlike family guy were every episode makes you laugh your ass off with things that you lease expect would make you laugh
South Park has been better longer and tends to be more intelligent actually. Even though it can be vulgar and seemingly immature, the jokes are often all satire and social commentary and pretty funny. So, ya, South Park. Though I haven't watched TV as a whole in a long time.
I don't like Family Guy. I can watch it as something to fill the time but I just don't get the humour... there aren't any jokes to me. South Park is more crafted - they pick something and go with it for an episode. It's the little touches of South Park, makes me cry with laughter!
