I love the supersteels, and I enjoy the knives I have with S30V and ATS-34/154CM blades. Still, many of my favorite knives have AUS8 blades. What's more, one of my favorite carrying knives, the Cold Steel Recon 1, has a coated 440A blade. My Cold Steel knives are all kept razor sharp, including all the 440As (ProLite, Night Force) and they keep their edges fine. There are some knives, like the CRKT, that sharpen "okay" and are only marginal in keeping their edges, but it varies. I have two M21s that hold a good edge, but they're nothing to write home about. The Voyager line of Cold Steel, though, holds a very fine edge. Even their little "medium" size knife works just great.
The same steel can turn out many different ways depending upon how it's treated and who treats it.
