I much prefer Family Guy. I used to love the Simpsons for its amazing humour, but with the more recent seasons it's seen such a rapid decline in actual enjoyable moments that I don't watch it any more. I still enjoy the originals however.
Family Guy is pretty much a watered down simpsons, got a fat guy father, a wife that somehow puts up with his antics, a daughter that usually is the butt of all the jokes, a son that has varying levels of insane [think Bart as being chaotic neutral, and Chris as being chaotic stupid], a baby that either is smarter than he/she looks or actually is, and lets not forget the dog. didnt stop there though, MacFarlane then ripped off his very own ripoff with American Dad which follows the same formula.
I loved the simpsons, since I dont actually watch TV anymore I cant say I still love them, but if confronted with having to watch either a 24 hour marathon of The Simpsons, Family Guy, or Futurama, I would have to say simpsons, at least with 13 seasons or more worth of episodes you could get some variety
