For me I switched from 3.73 to 4.10 and it made the car a lot easier to drive on the street. Agree that first gear is a little short now, but with 3.73's, sixth gear was useless unless I was going faster than 75 mph and was on a flat road.
I have the T-56 with 2.66 first gear and a 383 SBC with a aggressive cam, so I personally needed the higher rpm.
