I suspected the OP wanted the “perception” of greater stopping power rather than actual greater stopping power. Less pedal effort from higher coefficient of friction brake pads will give this perception.
@anon86613489 and @keith are both right on the mark. The pads are just one link in the chain. The tires are the primary element in the braking system for a single stop. For multiple high speed stops, the size and design of the rotor plays a large part as well as the calipers.
The ABS is pretty much a non-player here. It will work well until you get to the extremes of racing. It is designed to be as insensitive as possible to changes in conditions and tire design because you can’t control those things once the car leaves the factory.
Except it doesn’t create heat faster. It is exactly the same if the speed and the stopping distance are the same. The pedal effort will reduce with more aggressive pads.
If the stop is quicker, the energy put into the brakes is still exactly the same but the time to cool off the rotors is a tiny bit shorter. Makes very little to no difference.
