in the king Lear Edmund, Goneril, Regan- who is the most interesting? Why?

I've always found Goneril to be the most interesting because of the way she manipulates the actions and ideas of those around her, and the fact that she is so successful in her actions. Goneril isn't likeable, and she's by far no one you'd like to emulate, and yet, she seems to be the ultimate actress. She henpecks her husband and belittles him..... she sees him as weak and cowardly..... but he still gets sucked into her plans. Regan sees her sister as a role model and unquestioningly follows her lead. That's what I find most interesting about her....... her influence over the other characters is fascinating.
