Modulation is amount of lever pull force that translates into how much braking force is applied. Hydraulic disk brakes are better because they remove the cable from braking, and are not affected by riding conditions.
Because of how a master cylinder is linked to a brake piston there will always be a linear relationship between how hard you pull the levers and how hard the piston pushes the pad onto the rotor. Which has a liner relationship with how much friction is generated.
This also means that if you didn't mind using steel rims, traditional ceramic or metallic brake pads and used a hydraulic rim brake caliper they would perform equally at modulation and stopping.
Hydraulic Disk brakes are also superior because they use steel as the braking surface, making them durable, capable of withstanding much higher heat, and isolating that heat from the tire.
Also why are roadfags still arguing about this. Where stopping power, heat management and consistancy are required (motor sports) hydraulic disk brakes are used exclusively.
