No. A stepper, by definition, STEPS. The "linear" move, expressed as a
graph of velocity-vs.-distance moved is jagged like a saw-blade, or
stair-stepping. If you need to "get down to where you compare one to the
other" in this regard, it begins to depend entirely upon lead-screw pitch,
reduction-gearing between screw and motor-shaft, etc., etc., etc.
