I think anyone who drives off-road in the mountains knows how much better sticks are then automatics. It's extremely frustrating to take automatic trucks on steep off road terrain.
No need to work my left foot like a drummer in a speed metal band.
Having some sort of terrain response system like just about any current 4x4 does makes it even simpler.
How much better for what? You missed a qualifier there. For exact control over torque-vs-speed - Yes. For the comfort of driving - No.
