Me too, never used steppers unless no other option.
Out of interest this is the resolution presently used by Fanuc on their Alpha motors since 2002.
Which is a mixture of absolute and the lower value incremental.
Prior to this, going back to 70's/80's they typically used 2000 pulse/rev incremental for the vast majority of applications.
