This has been AMG's argument for the MCT: way smoother, way more capable, and in the latest iteration, just as fast as a DCT with a new 9 speed coming out.

It's an interesting case from a dork perspective: wet start-up clutch pack like a motorcycle, then individual clutches on each of the 4 planetary gear sets for "double de-clutching":

One drawback of planetary transmissions is that they have a lot of high speed rotating mass, which hurts engine response and slows acceleration. I guess part of this can be offset with a lighter engine flywheel.
