It was discussed by AMG engineers on the private lounge in response to a question as to why the new SLK used the 7G and not the MCT. There's a number of responses from the AMG engineers over the two pages.

Bottom line you probably won't notice the difference and will enjoy it either way.

With seven gears, up to four transmission modes and the double-declutching function, this transmission enables extremely dynamic acceleration and ultra-short shift times, as well as a fuel-saving driving style. Depending on the preferred driving style, the driver has a choice between efficient and comfortable in transmission mode "C" (Controlled Efficiency), brisk and sporty in "S" (Sport) or manual in "M." Gear shifts are executed with virtually no interruption in tractive power. Partial cut-off of individual cylinders during upshifts allows extremely sporty gear changes in less than 100 milliseconds. Depending on the model, the transmission additionally features the RACE START function, which supports optimal acceleration from rest or from the starting line in motorsport events. Ultra-fast, responsive multiple downshifts are another forte of the AMG SPEEDSHIFT MCT 7-speed sports transmission. For instance, kickdown allows the driver to shift down directly from seventh to fourth gear or from fifth to second. Transmission mode "C" allows comfortable driving at low engine speeds. At the same time the ECO Start/Stop function is available. This enables fuel consumption to be effectively reduced.

MCT stands for Multi-Clutch Technology, indicating that only clutch elements are used to perform gear shifts. The conventional torque converter is replaced by a compact wet start-up clutch, which runs in an oil bath. Thanks to its low rotational inertia, the transmission responds instantaneously and dynamically without the losses typical of a torque converter. This helps to reduce fuel consumption. In addition, the sports transmission impresses with its low weight of 83.2 kg, including oil. This is made possible by the use of lightweight magnesium for the transmission housing. A two-stage torsional damper is responsible for effective vibration isolation.

Ultra-fast, responsive multiple downshifts are another forte of the AMG SPEEDSHIFT MCT 7-speed sports transmission. For instance, kickdown allows the driver to shift down directly from seventh to fourth gear or from fifth to second. The automatic double-declutching function is active in transmission modes "S" and "M." Every manual or automatic downshift is accompanied by precisely metered double-declutching – from "S" to "M" incrementally. This not only heightens the emotional appeal: the load-free downshifting procedure minimizes load cycles, which has a particularly positive effect when braking into bends and improves handling safety on wet and slippery surfaces.
