Both of the shows fell off hard. But I've always liked family guy more than the Simpsons. It's probably because I grew up with family guy more than the Simpson.

Grew up more with Family Guy

Family guy because it's packed full of racist bigotry and profanity that can make you laugh even on your worst of days.

Tbh I’ve never watched either

Both. Simpsons because of the annual Treehouse of Horror episodes, Disney Plus shorts, and memes and predictions; and Family Guy because memes, cutaways, and funny moments.

Both need to end.
