While I think Cruella's just freaking insane and thus insensible, and while I have a soft spot in my heart for Maleficent (her performance is sculpted, yes, but very controlled, and I'm not sure she has a sense of humor... or rather, it's a very mean-spirited one), I really love Ursula and Yzma. They just crack me up; Ursula, because she knows she's playing to the camera and revels in it without apology, and Yzma, because she seems so cluelessly stupid about the rationality of her plans and yet seems to bathe in her megalomania.
EVE's not much of a villain.I like EVE better.
But I think she's awesome.
Probably a better fit for you too, rather than the ESFJ (AKA "Lucy Van Pelt") from "Alice in Wonderland."
