M mode is reportedly the fastest shifts which this article about the Speedshift MCT 7 speed trans technology explains.

A regular twin-clutch unit could not handle the level of torque developed by Mercedes-AMG’s V8 units, so this solution had to be designed to obtain maximum performance.
The innovative component introduced by Mercedes-AMG’s Speedshift MCT-7 unit was a “wet start-off clutch,” which operated in a sump to aid cooling and longevity. The component has a low rotational inertia that allows quick response times, which cannot be matched by liquid-filled torque converters.
MCT stands for Multi-Clutch Technology, and those clutches are the sole executors of gear changes. In the Manual mode, the gearbox managed to shift gears in just 100 milliseconds. That is incredibly fast, but the unit also had a comfort mode for day-to-day driving, as well as two sport modes.
The first of them was 20% swifter than the Comfort mode, and the second Sport mode was 20% prompter than the previous. Meanwhile, the Manual mode is an extra 10% quicker than the S+ mode, which was the most rapid automated operating mode of that transmission.
The AMG Speedshift MCT 7 unit is even lighter than the AMG Speedshift 7G-Tronic unit, which is employed in other products of this division. The MCT unit weighs 80 kilograms, and it can operate at engine speeds of up to 7,200 rpm. Only the high-performance vehicles from the AMG line have been fitted with this type of transmission.

The Sport+ mode is way faster at downshifting then manual. Most times the manual wont let me downshift fast enough when braking. I basically use Sport+ on the highway and Manual mode when I'm on the twistys and wont more control over my engine RPM
