Each of the current candidates has a flaw. Not necessarily a bad one, but makes them "not ready" for such a promotion. Either it's lack of experience, or simply not capable of holding such "power and command" (Clearing up a point; I wasn't perfect either, nobody has been. But judging by my own experience with administration at least and the people I have spent 3years of my life with).
This is not a best of the worst scenario, but if anyone then definitely Psychotic in my opinion.
