Gimbal for astro?

Question for the experienced: how effective (or not) are gimbals for shooting astro, specifically motion lapses of the Milky Way etc? I'm familiar with other gear for this (sliders and pan/tilt heads, etc), and I know that trackers are the best for this kind of thing (though much more soecialized), but most gimbals I've seen have built-in interval timers and programs for timelapses, hyperlapses, and motion lapses. I've seen only a couple of videos of people who have tried astro but with mixed results.

Maybe a more specific, technical question. An astro tl requires long shutter speeds and of course an interval between shots. For a motion lapse, I would want to set an A and B point, say for following the Milky Way across the sky. The gimbal would control the camera to take the first shot, then during the interval the gimbal would move incrementally and take the next shot, and so on. So:

* are gimbal motors able to move in small enough increments and then hold that position without moving the camera? Would a long enough interval between shots allow the motor to "settle", or are the motors in constant tension (if that's the right term)? In many gimbal reviews I see the term "micro jitter" and wonder if this is what the cause is. Are pan/tilt heads such as the Zeapon Pons/Syrp etc better for this application, and why? I'm asking because I'm just a hobbyist and some gimbals are within my budget range, and are much more portable, whereas full motion control systems are not.

Thanks for any replies and insight
