Nonsense. DCTs provide better performance. It's just that many "driving enthusiasts" have conflated the extra level of complexity with control.
Many people who enjoy driving aren't overly concerned with performance numbers. It is the act of driving and getting things right, being entertained/engaged and being responsible for the way the car acts yourself.
DCT removes an entire skill set (heel+toe, clutch kicks, etc) that can be used to alter the attitude of the car.
If i want to clutch the car into a smoking tail slide with a stick and a clutch pedal, I can. If i want compression lockup to back the car in sideways into a corner, I can have it.
I don't care if it is faster or slower. Those who look at 0-60 times and harp on about how DCT is 0.2 sec faster or whatever just don't get it. Don't care, DCT takes away so many options for me to
play with the car. And that's what a performance car is for. Playing with.
It's a big toy.
Ditto for traction control, stability control, etc.
Just like understeer tendancies are safer for a muppet. Having a car that is more neutral gives the driver more options to play with - neutral through the corner or smoking sideways into and/or out of it. Or even far more subtly, being able to adjust attitude mid corner with throttle.
For me "performance" is about how much I enjoy driving the car. Not fractions of a second in 0-60.
I ride a bike as well... every day for 6 1/2 years on the road.
