Differences in brake materials has have limited immediate consequences.
What will change is longevity, pad wear, visual effects, rotor wear,
noise, smell and other irrelevant consequences to the actual need.

With respect to "stopping distance", in the Michigan Police Cruiser study,
they controlled for identical deceleration (thus identical stopping
distance) and measured pedal force.

This is a different test than applying a uniform pedal force and measuring
stopping distance.

I'm not sure how to extrapolate that information to stopping distances.

I would have thought that as long as the driver & brake servo can apply enough force it would make no difference at all to stopping distances.
