Just to name a few.
The G3 hub weighed less than a stock Shimano Ultegra hub, and way less than a 105 hub. In addition, you didn't need a separate speed sensor, which saved another 35-40 g (depending on which speed sensor you buy). So even the lightest alternative, a single-sided Stages or 4IIII added weight while a PT G3 hub could subtract weight, depending on what stock hub you were replacing it with. And it measured total power, not just one side.
