Diamond does leave a deeper stria, cuts faster and can feel harsh on the skin as the deep stria creates a micro saw tooth edge.

Chrome Oxide and CBN of the same grit size leave a shallower stria and less of a saw tooth / straighter edge, more comfortable on the skin.

So it depends on what you are trying to achieve with your edge. I have used diamond to refresh an edge followed by Chrome Oxide for comfort and CBN for maintenance.

Really at that level it depends on your face and the razor’s edge.
