The sensored startup is one of the smoothest around. Sensorless startup is good, but the mamba shuffle still shows it's face once in a while. So a good sensored motor is recommended for instant starts. Kinda messes with my reaction time.
With sensorless motors I can watch the tree light and anticipate when the car will move. With sensored, I actually have to slow down my reaction before I pull the trigger. Something I haven't/can't mastered yet. Might be getting to old for it.
