I'm very happy that I chose AT. And the fact that it gets quicker from 45 to 60 - just tells you that direct 4th gear (vs direct 5th gear in MT) was the right call on engineering side.
AT gear ratios + diff, makes it very good driving experience. It will loose MT from 0 to 60, but will win if cars moving at least 20 mph. So, call it a tie
