Like most of you folks, I have alot of knives in various blade-steels, and here's what I have determined from experience:
Blade-steel does matter, but the blade grind, thickness, and geometry matter even more.
I find that AUS-6 and 440A are both too soft to hold an edge very long.
Of all of the blade-steels I have used (AUS-6, AUS-8, ATS-55, ATS-34, VG-10, 440A, 440C, 420HC, and others)...
VG-10, ATS-55, and 440C are my all time favorites.
440C is not inferior.
