Mora use 12C27, which isn't a bad stainless, a lot of very experienced makers and users like it but it is a cheap steel, and only gives its best with cryo treatment (source-Alan Wood & Mike Lamprey). As treated by Mora the stated hardness range is 56-58HRC. At 58 it will be reasonable, at 56, poor. By comparison, the carbon steel version is hardened to 58-60HRC. It is quite possible that your comparison blades were quite a distance apart in hardness.
It is a shame to tar all stainless steel with the same brush based upon a sample of one. Don't discount the idea of making yourself something in a high end stainless one day. That is what I did. I have used essentially the same knife in O-1, 12C27 (cryo) and RWL34 and for general use, the RWL34 has been the winner.
This makes interesting reading.
