You may like the CrO better than the diamond or vice versa, you may have to try them both to know.

I did not like the edges off 0.25 micron diamond spray, for me too harsh. From what I have seen...

I'd say t is a question of preference of the type of edge you get, it was for me at least. I liked diamond spray edges better than CrO.
When you learn how to hone correctly you will need neither.
