Best SNL cast member of all time: Chris Kataan or Molly Shannon?

I also think neither of them but given the choice, Molly Shannon gave more to the show with her Sally O'Mally ("I'm 50, 50 years old") and Mary Catherine Gallagher which resulted in the movie Superstar. She really showed what women in comedy could do...and who could forget her part in one of the most infamous sketches "Shweaty ".
