What alot of people are forgetting is that alot of us are now using wider stickier tires. This increases the static friction coefficient and therefore makes the car stop faster, if you can come near the static friction limit of the tires with the brakes. The stock brakes had a very hard time trying to stop my wheels and tires. I could literally MASH the brake pedal and the tires would not lock (I don't have ABS). The stock brakes were designed with the stock tires in mind. After my new brakes I can lock the brakes but only at the very last bit of pedal stroke. This for me is ideal. But you have to realize that upgraded brakes WILL stop you faster if you have wheel and tire upgrades that will allow you to utilize the brakes better. But as others said the main benefits are the increased thermal capacity and hence the more consistant braking and lack of fade.
