It depends; the MM controller are pretty sensitive. rumour has it that that Y winds run better on the MM controllers. While some people don't notice any cogging on their neu/mm setup others are experiencing a nasty cogging. According to the engineers at castle the Neu motors are slotted motors and need a software update on the MM, which isn't available yet, since they are focussing on the MMM and the Neu type of motors. I am sure that once the MMM/Neu clone is launched the MM will get a 'slotted' option in the software too
