Favorite gear ratio for street car

My 95 5.2 Dakota has factory installed 3:91s & It cruises well, around 3200rpm at 70-80 mph, but I do have the O.D. 4th gear & that helps a lot. I like the 3:91s for the street. If the motor is built right, you won't have any problems. It will run at 4000 rpm all day long, easy.
