Stainless steel is better than regular carbon steel in at least one important aspect. Stainless rusts at a very much slower rate. I hone and shave with razors made from both types of steel and can't complain about the shave from either. For me the argument as to which is better is a tempest in a tea pot. In everyday use either works just fine. Knife makers and aficionados seem to obsess over what types of steel make the best blades. OTH razor users don't seem to be as afflicted by that syndrome. Now, brushes and soaps on the other hand are a different story for shavers.
