As someone who has driven cars with a gated shifter, I'm here to tell you that the novelty wears off in about 3 shifts.
1. The contact "click" is terribly annoying.
2. You have to navigate the gate, so you end up shifting slower
3. You miss shifts (contrary to what you would think) because the shifter rides the gate which causes you to accidentally go 4-3 instead of 4-5, or 5-6 instead of 5-4.
