I like both of them evenly because family guy has ups and downs with the newer shows but some of the shows make me crack up. But southpark has alot of trend setters or makes fun of big things thats going on in life right now thats so true and pretty funny.
South Park, but really only the first 7 or 8 seasons. recently it got a little too satirical and is a little annoying. still, im a die hard south park fan. especially the episode that makes fun of family guy XD
