Tough to compare. Simpsons is a classic but definitly been on a down trend the past 2 to 3 seasons. Hitting hard when they hit but missing big when they miss, plus they are starting to recycle storylines and are not ashamed to admit it.
Futurama is a little harder to get into cause some of their humor is a little more bizarre and sometimes colder. But I like it alot and I think it got cancelled at the right time cause it never had the chance to get old and played out like the simpsons are becoming. And even though they have the same creator the style is too different to compare.
I give thumbs up to both as I own all the dvd seasons currently out for both shows. If you didn't like futurama before, give it another shot. I promise after 2 or 3 episodes you'll be laughing your arse off.
