It is not all about "clamping force".  Good brakes absorb energy - how?  Heat dissipation.

More piston area (as you said - please give us the numbers!) will allow more surface area to dissipate heat.    They may or may not also have one piston contact first which can help with modulation (do they do that?)

I tend to believe the science here.
However, perception is reality to some extent.
I wonder if what people are experiencing is vibration damping and not compliance?

Ah so that's how Magura get's the brakes so light!
