i agree, but being a vampire has drawbacks, same as werewolf, vamps need to feed to blend in public, and take sun damage, inconvenient, not sure bout werewolf drawbacks as i havent really experimented, i think u uncontrollably transform or something on some nights, liches traditional ones dont have any drawbacks other than being a skeletal robed corpse, with magical properties over the undead, they require no sustinance, basically their only drawback is their appearance, but through powerful illusion spells they could cloak themselves to blend in to complete quests, but actually living in a city or town would be ridiculous, there more reclusive in nature.
Proper wolves are supposed to transform during the full moon (a number of people will carry Hircine's curse ring for the random transformations). Only major drawback is your health doesn't regen very quick unless you feed. Stack enchantments and powers, there isn't anything I haven't been able to take on (Master difficulty to boot).
If I was magic oriented it'd be a toss up between lich and vampire. More than likely lich since they aren't bad with sunlight and they probably don't have to play with Molag Bal after they die...
Immortality would svck after a few hundred years...
