Hence, depending on how good you are managing a launch, you can hook the tires easier with a longer 1st gear in the 6MT in addition to being able to manage the rate of weight transfer to the rear with the clutch engagement.
Secondly, the DCT carries 55lb weight penalty everywhere, so it's power/weight ratio is 1.5% less than the 6MT.

As for launching any manual I always was a bit conservative on launches. Consistency wins almost every time. Again a DCT is more consistent.
An autocross run is like sailboat racing. The person that wins is the one that makes the fewest mistakes. There are fewer variables with a DCT than a 6spd.
I'm a 6 speed fan, but on a Solo 2 course I'd opt for a DCT.
YMMV,
