Actually DCT does both. In the more aggresive shift modes, you get that "kick" while upshifting. This is the transmission recuperating the inertia of the engine's RPM drop and transforming it in forward thrust. Essentially a power shift. So yes, better performance. If the sensors detect that the car is laterally loaded, DCT will do a butter smooth shift as to not upset the chassis (even in the more aggresive settings). This is only possible with the dual clutches as there is no interuption of power transmitted to the wheels. Impossible to do with a MT .
