I like them both… they both have their ups and downs. South Park episodes that mostly feature Stan and Kyle tend to blow…. the best episodes being the ones where Cartman, Chef, Butters, Stan Marsh or Mr Garrison take centre stage. The topical humour can be brilliant but sometimes I think the writers are off their faces on smack when they are thinking of plots. Lemmiwinks ❓
Family Guy has the best one liners though, they tend to rely more on timing for comic effect. It can piss me off though when the episodes go nowhere, the pointless comical irreverence has been overdone.
The early Futuramas are great as well.
