I have first hand experience with Ultra, M600 with metal gear, M600 with quiet gear. With metal gear the M600 is obnoxiously loud. Many of those claiming it wasn't that bad ended up switching when Luna came out with the quiet gear. With the quiet gear the M600 is acceptable, I'd say slightly louder than the Ultra, but with a somewhat different tone. The M600 with quiet gear is more of a fluty tone. Since you can get the quiet gear I'm not sure I'd worry too much about the noise. It's the lack of programability and substandard torque sensing to worry about as those are harder to fix. Supposedly there is new bafang firmware, but you need to get your hands on the BESST tool to flash it, assuming you can find anyone willing to sell it. See the M600 thread on ES:
I am hoping to eventually flash the 43V firmware (only downside seems to be battery % will display wrong, but no biggie if you monitor volts). If that doesn't fix my issues I will pay the piper when innotrace comes out with a controller for the M600.

Since this seems to be an interesting motor, why not have a separate topic for it? I'll start with three quotes I have found about the motor on this forum, feel free to add more information that you can find. Over the last couple of days I had heard that there had been reports of the M600...
