So you mean "normal" wheels aren't 100% efficient either because the field surface shifts backwards when the wheel drives forwards, right? I'm not sure that makes much of a difference between the two wheels.
Do we even have a definition for "efficiency" in this case aside from the arbitrary demand that all force vectors should be pointed in the direction of travel because we think that's efficient? In that case, I'll point out that mecanums are vastly more efficient at turning than a 6WD, and thus are obviously superior by my idiosyncratic definition of efficiency.
