I agree with this (other than the comment that a DCT is crap in traffic because it isn't and is actually fairly smooth)... I believe the M-DCT might be faster (could be wrong) but at the speed in which they both operate it would be irrelevant. I also do agree that the 8AT is easier to live with day-to-day. The MCT transmission in the C63 is also very fast shifting (quoted at 100ms) which is likely similar to the M-DCT but it is no where near as "connected" or fluid in manual mode as the DCT.

A DCT's advantage is its feel and connection with the car in manual mode and that is the only area where no AT can really compare. The DCT feels and acts like a true manual (because it is) and feels like a direct link to the car. In manual mode and in aggressive driving it is incredibly fun in a way an auto can't match yet. Driving around town, this connection and responsiveness is much less relevant and the DCT isn't as good in those circumstances for sure.
