While as quoted these statements can both be true, I think it can be mis-interpreted as mecanum has less power than 4WD or 6WD. Driving straight forward or backward there is no power loss in mecanum. In any other situation where mecanum has power loss we are talking about motion that 4WD or 6WD can't do at all, so power loss does not say that 4WD or 6WD is therefore a better choice. (alternatively, I could say 6WD has 100% power loss while moving at a 45 degree angle while mecanum only has a 50% power loss) As long as your driver realizes driving all the way down the field with the robot at a 45 degree angle relative to the field would not be a wise use of mecanum, then power loss is not a real concern when deciding mecanum vs. 4WD/6WD.
