The bigger brakes don't provide more braking force, you would not see a difference in stopping distance on the street. Both brakes are limited by tire traction.
Bigger brakes only shine over smaller brakes when they are under consistent use, it's about heat management and the ability to resist brake fade and remain consistent. Big brakes have bigger rotors and more pistons applying pressure (generating fiction heat) more evenly across the bigger rotor surfaces. Bigger rotor surface can take more heat and dissipate heat more efficiently.
If 2 M2Cs went to the track, 1 with the blue brakes, 1 with the silver, the braking ability might be the same for the first few laps, but at some point the blue brakes will start to fade as they get hot, brake pedal will go spongey and the brakes will no longer consistently slow the car at the same rate, the tire traction is no longer the limiting stopping distance factor. As they cool down the braking capability quickly returns. The silver brakes will also fade but it will take longer (more laps) the average none pro-racer might never reach the higher threshold.
If you like to go to the track it's a pretty big deal that they put these brakes on the M2. If you don't go to the track and you have the ability to spec the car with the blue brakes you should to avoid the unsprung weight penalty.
