Just off of the top on my head, you'd have twice the hill climbing power and acceleration at speeds below 25mph. That doubled torque would start to wean down after 25mph to about the same torque as before at around 40mph and continue down to about 60% of original (so about 2mph per second acceleration instead of 3) at around 50mph. It would be much less and limit at higher speeds and limit you from going much faster. But all in all, I think that if you were wanting a more practical vehicle the 2:1 ratio before the differential would be best. You'd be limited to a top speed around 55mph but at slower speeds it would feel more like a normal car.
