A lot of accomplished photographers don't know much physics.

I'll give you a counter example where FF + f/4 is superior to APS-C + f/2.8.  The case is landscape photography on a tripod or any other situation where light permits base ISO for both systems.  FF at base ISO beats APS-C for IQ, assuming equivalent sensor technology.

All the equivalency arguments assume the FF is shooting at a stop higher ISO to compensate for 1 stop smaller aperture.  Given enough light for base ISO this argument goes out the window and FF wins every time.
