Even just limiting it to the current cast is tough. If you factor in the women from decades past it's well nigh impossible. Gilda, Lorraine, Danitra, Molly, Cheri, Jan, Nora, Ana.
Of the current cast, I adore Maya, but if I had to pick just one, it would be Tina. She's smart and funny and sarcastic and I got to see her host a major gala at the Just for Laughs Festival in Montreal last summer and she is just as fantastic out of the SNL element as she is in it. (Rachel dropped in as special guest that night, and she was fab too.)
