IME, good 420HC is like good Sandvik 12C28 and both are fairly comparable to good 1095 in that they sharpen easily and take a very fine edge. If the knife is going to be used for whittling or wood working I would think that's a good stainless option. I don't fully understand the issue with balking at the high prices if the price is buying you the fit/finish one is looking for. People pay that for 1095 and I can't imagine that 1095 is any much different than 420HC or 12C28 in terms of production costs. The big issue is heat treatment, I would think. Totally agree with others that Case's 420HC leaves a lot to be desired, but again, that's a heat treat issue.
As I understand it, 440C and D2 are both large carbide steels. Harder to sharpen and perhaps happier with a toothier final edge. Great for rope and meat and such. But I wouldn't see them as being better. Different and better for different uses, yes. But not carte blanch better. Just a different category (large carbide vs small carbide).
