A bigger break gains no advantage from being able to squeeze harder.
I do think that larger breaks might give you more control of how hard the breaks squeeze allowing you better control over breaking force without locking up the wheels. Is this the difference?
My thoughts above don't take into account heat build-up during breaking or ABS. I realize bigger breaks would spread the heat out more and fade less and I don't really know what effects ABS might have.

First off, it's "brakes," not "breaks."
"It seems to me that breaking is more about friction between the tire and the road" That's not correct. Braking is about the friction between the brake pad and rotor. Therefore, bigger brakes -> more surface area -> more friction = better stopping ability
