Family guy has some very clever humour but is mostly beefed up with random interchangeable jokes (as parodied on South Park - Cartoon wars)
The Simpsons during it's peak years contained some of the best TV and comedic one liners ever written, and it achieved that whilst being suitable for all the family. This is genuinely upsetting.
Definitely Family Guy. The Simpsons has been stinking for about 10 years.
I'm still in the habit of downloading and watching the new episodes of both and you barely get a laugh out of The Simpsons. Not to mention when they do stuff it is severely dated, like the Pokemon Go episode about 1 year after the craze has died down.
Family Guy gets away with it because it's more mature theme and has more leeway with jokes and storylines that way imo.
The best of the Simpsons is probably better than the best of Family Guy. Unfortunately the best of The Simpsons was probably 25 years ago. The current crop of writers on The Simpsons are folk who have grown up watching the show and it feels stale. Family Guy isnt as good as it used to be at its very best but its still very watchable. I honestly doubt I could sit through a new Simpsons episode these days.
Family Guy for me, still watch the Simpsons but tend to just turn over unless it's a classic. Once found the uncensored Family Guy (season 7 I think), hilarious, wish they would show them all like that.
Ive gone off South Park these last couple of seasons (hoping for a return to form this season) but overall it's by far the funniest animated show IMO. Can't wait for "The Truth Butt Whole" game too
The Simpsons from series 2-10 has a very decent shout of being the best sitcom of all time, animated or not. It's shit now but it had some run of quality.
Family Guy has some cheap laughs using puerile shock humour. It never has and never will get near the quality of writing the Simpsons used to achieve.
The first 8 series of The Simpsons is as good as funny TV ever got. Far surpasses Family Guy. Unfortunately, its now a shadow of itself and this makes it harder to remember how good it was.
Both have faded, the Simpson's badly and it pains me when my kids watch the newer episodes. I honestly believe Simpson's series 1-10 is some of the best TV ever made.
Simpsons seasons 3-8 are some of my favourite tv of all time. I enjoyed the early seasons of Family Guy but even at its best it doesn't come close to peak Simpsons imo.
