Regarding the other post regarding AT with wider gear spacing being faster than narrower gearing on a MT equivalent, that's entirely believable if the car has a broad torque curve. You see the same thing with Camaros, Corvettes, etc. You need close gearing to optimize a narrower power band, 370z's and GTI's likely don't have that issue. Not sure about the Nissan, but pretty sure the VW is dual clutch too which avoids the losses associated with "slush boxes" (I think I'm dating myself with that comment!) in these cases your shift times are often better than your typical MT driver, and you probably have some sort of launch control. Yay computers!

Our torque band is flat once you past the torque dip in which the shorter FD keeps the revs higher from 2nd gear all the way up. Also a Header and tune would essentially make our torque band become just as flat as a 370Z.
