If so, that would imply that a well-done heel-toe downshift under braking in a manual transmission car is smoother than the rev-match of DCT.
A downshift isn't as smooth in S5 as it is in S4. On a straight, no problem. I've ran into 2 scenarios where S4 works better.

1. Hard braking zone, S5 can cause the rear end to wiggle or wiggle more whereas S4 makes the car feel more settled.

2. MSR Houston has either a left/right or a triple left followed by a fast sweeper onto a long straight. When you enter into the sweeper, you're on full throttle but you still have to turn the car a little. An upshift in S5 can upset the car...S4 its buttery smooth with no drama.

No...DCT beats 6MT 100% of the time
