I've compared my 78 to the Custom Custom many times as I have a Strat with each as the bridge pickup. The 78 is slightly lower in volume/output and has more texture...more tooth...like the teeth on a comb sort of. The CC is thicker and smoother and more syrupy. Both allow me to shape the note with my pick and squeeze it out. I like the CC when I want a hotter pickup and just want to wail and I like the 78 for pretty much the same thing but maybe with a little more open and textured tone. Lew
