If the driver and driven are the same diam, no matter how small or how fine the pitch that is used, the resolution is still the same.
In my cutting laser I have a 3:1 reduction from stepper to the driven ass'y. This reduces my speed by 3X, increase my torque available by 3X and increases the resolution by 3X. In my case, I didn't need speed. I can move my 5lb gantry at speeds over 800 ipm which is way way to fast anyway for cutting.
