So yes cooler running both at the drivers and the motors than tmc2100, quieter than A4988s but not as much.
Oddly they seem quieter at 1/32 certainly a huge amount quieter than drv8825.
I'm running my extruder on 1/2 stepping and its still reasonably quiet, so these drivers must do some sort of interpolation.
Prints coming out quite sharp for petg, no layer shifts
