Two obvious differences requiring no explanation are maneuverability and storage space.Why do you think that? I have a 3 point and it is fantastic. A 3 point keeps the noise, the flying grass away from the operator and a bonus is no wind rows because of the wide rear discharge. I can't see a comparison between MMM and 3 point other than they both cut grass.
The OP complains of poor cut quality in the front wheel tracks. Though we do not yet know the reason(s) for this, it is reasonable to assume that this anomaly will not be improved when both front and rear tires travel over the grass before cutting.
