Yes, definitely best edges as far as cleanliness will be with diamond, that much is pretty evident. That doesn't mean that a comfortable edge won't be achievable on other stones though. The carbides are awfully small, so as long as they aren't torn out creating a very ragged edge in too high of a percentage of the edge it probably won't even be noticeable in a shave. Ugly scope shots of edges that shave pretty well are not that uncommon.
As far as substrate, I think a soft substrate may do just fine. The diamond particles are so small that I think they will still be able to reach the pressures needed to take their nibbles out of the carbides. I can try it anyways, I have plenty of diamond lapping compound laying around as well from my machining and toolmaking days.
