No surprise that Burrow poo poos on the Simpsons
As for the Family Guy comparison, Simpsons I've always enjoyed more in terms of storyline, characters, etc.
When it comes to quick jokes, shock humor and things of that nature, it is obviously Family Guy.
The Simpsons, however, does not contain so many cutaways, musical numbers, chicken fights, Peter wasting time doing nothing, etc. Simpsons does not have as much dead time in their show.
I still think Futurama tops them all, personally.
