I'm partial to Stirner as well, and think he does a better job of the fundamentals of conceptual hygiene than Nietzsche.

But with Stirner, you're liberated from some conceptual errors, you're free to value without conceptual handicaps, but left with a "now what?" on how to do it. Nietzsche at least takes a stab at new values, though I maintain he creates some of his values for those he feels are inferior and allow values to be imposed on them in their conceptual confusion. A Will to Power, even in philosophy.

One other thing I'll say for Nietzsche. I find him quite funny. The Philososopher Comedian. Chapter titles: Why I write such good books, Why I am so wise, Why I am a destiny. Gives me the giggles every time.
