Your favorite rear end/final drive ratio and why?

It all depends on the use of the car. Years ago, i had a coworker with a 71 Cuda,440 4 speed and 4.30 gears, he was always blowing MY Cuda this, MY Cuda that! I asked him how long he would take his car out at night, his reply-usually run thru a tank of gas, some of that racing fuel. One time he started blowing, I had just got back from a 1800 mile roadtrip one extended weekend with my 69 Coronet R/T, 440 auto, 3.23 gears. I asked him who he thought had the most fun, him driving around town for a couple hours with his 4.30 gears or I-that had just logged 1800 miles on the highway with my 3.23 gears. He didn't answer me and he never said another word about his Cuda, in fact he sold it a short tome later.
