CRKT can get real sharp, if you're lucky. cos of the polished edge. but use it for awhile, and Spydercos beat the shit outa them. Spyderco edges are "crispy" - they're real sharp but not polished. they'll shave / pop hairs, but they'll also cut wet rope or layers of cloth easily. try that with a polished edge....it won't work.
my sharpest knives outa the box has always been Spydercos, whether VG10, BG42 (yes, I agree that was SHARP), ZDP189 or S30V.
but the sharpest ever so far has been a zero ground Emerson followed by Bob Dozier's edge (and they were both "crispy" edges, not polished).
