Frankly, I can't say I've ever had reason to compare the two side-by-side.
As a parts specialist I know they are not interchangeable with the more common

The two ARE interchangeable as long as you exchange them as an assembly which
includes the necessary carrier.  The elemental difference between the two is
that the guide pins of the Girling caliper assembly are fixed to the caliper
body and float in the carrier whereas the guide pins of the ATE caliper
assembly are fixed to the carrier and the caliper body floats on them.

The ATE caliper assembly could be considered to be a better design because
the caliper body is not overhung as it is in the Girling assembly.  The downside
of the ATE design is that the guide pins are more exposed to the elements.
