It is indiferent if you have a hard or a softer stone.
Garnets size are the same.
The clay medium is different, probably and the garnets density.
As for finishing if you keep the softer stone always free from slurry you must have approx. the same results with the hard.
But it is easier to use a harder stone as a finishing stone and you have more consistent results with it.

But keep in mind that grit (garnet) size of a natural hone is not comparabile with that of artificial hones.
A belgian blue (4000) is not replace a norton 4000

This, is my oppinion only.
