Surely it's the consistency and shape of the teeth, and in general the overall precision with which the interior of the wrench corresponds to the exterior of the nut, that determine the spread of the driving force across the flats and the stability (and thus resistance to rounding) of the wrench. In other words, if a wrench fits the nut snugly, it's less likely to slip, and a well-made wrench fits better.
