I raise you Seymour.Also, the Simpsons had heart - wasn't always about the jokes, other two...not so much.
Maggie's First words episode for example....never get that from the others
Yes, I would say the Simpson's WERE the best, and I am not sure what IS the best. I vote Simpson's for the reasons you stated.The Simpsons, seasons 3-10ish are as good as anything created.
Family Guy would not exist without the Simpsons.Simpsons is a cultural icon, others not so much. Family Guy doesn't even belong in the same breath
