I don't like a specific type of vampires. I love one vampire, and that is Aduza-Daro. She has that normal khajiit charm but also as a vampire she has no problems with hurting people who opposes her.
I remember the first time I ran into her and she threatend to stab a guy "where the bright moons don't shine".
My altmer vampire eats a lot of apples and never kills those he bites.
(Really, he just cloaks away. I can only imagine how frustructed those NPCs feel.)
