Are taper lock pulleys a good choice for ball screws?

Even with motors of near the same inductance is proven.
Nema34, 1080oz (7nm and change) 3.5mh inductance:
Loud, bad resonance, max velocity 2000mm/min, stalls thereafter, Inertia causes 0.2mm overshoots at stop.

Nema24, 566oz (4nm) 3mh inductance:
Near silent, max velocity can exceed 3000mm/min, stops dead, accels like a rocket.

And here I thought it was all down to inductance.

Still have a 1080oz on Z, (2000 is quick enough there). Might need it for my spindles new servo motor (7kg weight)
Upping the power to 72V, might change driver to a stepperonline 100vdc input one (psu can go to 80).

Which drivers are you considering?
I have the CL86Y or CLA86T from stepperonline on my list of options for this project.
I could run them directly off 60VAC

Need to do more research but the CL86Y atm.
I'm still pondering about going closed loop later down the line. If this can run in open loop as well (for the time being), then I'll get it right now.

Otherwise it'll be the DM860Y as the machine sits, and then I'll look again at a later date if I change to CL.
