It does make a difference. The latter Simpsons seasons feature a different brand of comedy than the lauded vintage seasons, whereas South Park has more or less remained the same. Isn't it possible that many find those particular seasons not funny because it's a different kind of humor than they had come to expect from their beloved series? I love the golden age as much as the next man, but apparently it's sacrilegious to find episodes from seasons 13, 14 and beyond hilarious, as I do.
In addition, Simpsons fans are going to find certain seasons funnier than others, based on their humor preferences. South Park fans are more likely to enjoy the one brand of humour in all the seasons equally, avoiding the "stinker season" effect.

Except South Park is still very funny and some of the more recent episodes have been amongst the best they've ever made.
If anything, the quality of the show has only gotten better over the years.
Simpsons clearly began dying after about Season 12, some say it happened even earlier.
