Don, Plato? Without a doubt, tyranny. For democracy, one must consult Socrates and Aristotle. Perhaps Diogenes "The Dog," who once wandered into Plato's academy and insulted the master himself. I'd leave off Democritus.

And when you study these guys you see that these same two basic schools of thought have always been at odds. I'm with Socrates and Aristotle. A Platonic society is one that exists to serve an elite. That can never be a good society for the majority.
