IMO, the 4spd is more for the guys looking for the original look/feel of the car. With the proper rear ratio it can be usable on the highway.

5spd, one more gear...which allows for more selection of spacings between gears like a shorter 1st for take off and a taller 5th for low RPM cruising on the highway. I also choose a 5spd to allow for better spacing between gears when I cruise the mountains...I found the 4spd I had in my early 'vette left much to be desired between 3-4th when running around the hills.
