My 16 year old watches both Family Guy and The Simpsons. I have seen more than a few episodes of the Simpsons over the years. Think about how hard it is to keep any TV show fresh over what 12 or so years already? You are never going to have the greatest and best show every single episode, but over all the Simpsons has been a consistently well written fast paced show full of humor and a satirical view of pop culture in general.

Now what I have seen of the few episodes of Family Guy have been no where near the quality of the Simpsons. It's satire seems forced and shoved at you. The characters are pretty lousy and you simply don't care about them. The humor does not have the edge the Simpsons has maintained.
