Mises with methodology, Hayek with ABCT, and Rothbard with anarchism.
HHH even though I reject argumentation ethics.
Hulsmann is just so down to earth. I love his speaking style and I have yet to hear him utter a single word with which I disagree.
Murphy is sharp as a razor blade and usually right on the mark.

Mises; without him there wouldn’t be a Hayek (as we like him), a Rothbard, a Hoppe, etc. He single handedly ‘build’ Austrian Economics. (Compare Hayek/Rothbard to Bohm-Bawer/Wieser; it’s really clear how much Mises did.)
He’s also probably the best economist of the entire school.
Dolfuss.
Hoppe.
Mises.
Without a shadow of a doubt, Ludwig Von Mises. Human Action…

lol, no really, even tho I disagree with him on many issues, I really “enjoy” Rothbard. He gives a great glimpse into the political mindset of right-libertarians. I also appreciate his efforts in laying the groundwork for an entire political-economic system (that he believes to be) free of coercive influence.
Overall Hayek probably.
