1) If we're talking 3.5/Pathfinder heinousness, lich over vampire. If we're talking as-you-like-it, vampire over all the rest. I'm a fair(pasty)-skinned night owl to begin with, so adding some dark allure, cool powers, and a diet of blood (non-lethal, hopefully) isn't too bad a thing. Decadent lifestyle, and all that.
2) No clue at all. With a roll of the dice, we're gonna go with allip. I'm already crazy and mutter a lot, so I wouldn't notice the difference, at first.
3) Spherecasting. Covers all of it, negating the obligatory conflict.
