I think that the Black Shadow and La Lune stones are both microcrystalline quartz. I can say that, so far, I like the edge off of my Black Shadow better than the two edges I have from my Black Ark. But … different razor types and different steels are involved.
I’ve always been curious about La Lune’s myself. I don’t know that I’ve tried an edge off one, and general sentiment seems to be pretty positive
