KH Discs vs 73+ Discs

When you put that way, yes. Consider that I used to design brake calipers and other brake components for a living. then consider that "magazine test cars" are a well known phenomenon and aren't representative of actual production cars, especially in that era.

So my professional experience versus extremely suspect so-called "test data" from an enthusiast magazine? Its a no-brainer.

Despite the fact that the KH calipers have a smaller piston area? And a .75" thick rotor?
