If I were to choose between older, simpler South Park and newer, more satirical South Park then I would choose the former. But only just. They are a bit more hit-and-miss these days (More Crap was the worst episode ever, WTF was terrible, and The F Word was quite crap too) but when they get it right they are producing some of the best TV around - Fishsticks is one of the best episodes of any TV show that I've ever seen, and Dead Celebrities and You Have 0 Friends are awesome too.
