CYE is slightly better, but really I never like to denigrate Seinfeld so let's just say they're both awesome.
I get confused with Seinfeld fans that don't like CYE though.
Btw, great Kramer quote:
Kramer: I was returning some pants. I took a short cut in a subway tunnel and fell in some mud, ruining my pants. The very pants I was returning.
Elaine: I don't understand - you were wearing the pants you were returning?
Kramer: Well, I guess I was.
Elaine: What were you going to wear home?
Kramer: Elaine, are you listening? I never even got there.
I reckon I laughed for a whole two days when I first saw that ep.
