It must be frustrating to get the "good stuff" and not have it perform as well as the entry-level stuff. Something has to account for these issues. To rule out the ESC being the cause of the lack of performance, have you tried that same Quark on the 9XL? If it works well, then the issue has to be with the motor. Or, you could try the MM with the Neu if you can get by the initial cogging - just to test.
