Funny ones, they can be quite charismatic and more entertaining to watch. Especially I like the ones who act goofy yet highly sadistic at the same time (The Joker for example).

Dark serious villains are what I like.

I like PEs who are funny that are also charismatic and very entertaining yet very sadistic. Game changers on the other hand, I don't like them that much.

I don't think it matters that much to me.
