Another DCT / 6MT debate.... I think they both have their merits. As far as which one is quicker, I would be willing to bet that the DCT car would win 9x's out of 10 in a side-by-side drag race. It's easy to screw up the launch in a 6MT. I just sold my 6MT M3 after 4 years and am eagerly awaiting my new DCT. I fell in love with Dual Clutch transmissions after driving the GTR and Porsche's PDK transmission (wife's car is a PDK Cayman S).
