Yeah, the C63 7-speed MCT is a mostly standard automatic transmission (planetary gear set) except it replaces the torque converter with a wet clutch pack like on a motorcycle. On downshifts it "double de-clutches" which I believe means opens the wet clutch pack briefly while the planetary clutches brake/release to select the proper ratio.
Benz maintains that this arrangement is better for a daily driver sports car because it allows for increased comfort and efficiency at very little cost to performance ... with this latest iteration they could be right and Nick sure seems to think so. The real reason likely has more to do with economies of scale with their other transmissions as well as great efficiency to help justify the V8.
Note that (a.) the new 9-speed MCT is coming to the E class (already here?) and to the E63 so probably to the C63 and (b.) the GT uses a DCT rather than the MCT.

Very fair review and I think spot on. The present M3/4 vs C63 are more nuanced. It would be easy to see someone liking both. I liked and drove both of the last gen M3/C63 cars.
