New CNC Mill on the horizon

[JAZZCNC]

In a nutshell you'd get smoother movement from the motors, esp at lower speeds. Also less motor heating as they handle current much better and the drives software seems much more refined.
These things I know for sure just from the limited experience of the DM's vs AM/EM which I've loads of experience with.
While I can't answer this 100% because my experience with DM was limited I'd take an educated guess and say you'd get slightly less speed/torque compared to EM as well.
This said I still wouldn't sell the DM if you have them as the difference in use will be minor but there is a difference. The stall detect isn't an issue at all for you so don't fret about this and you haven't missed any point.
