If you are setting up a 9" chunk to put in your car for long trips

How does a 3.25 Galaxie rear stack up against a 3.00 or a 3.50? I have 4.33's that are in it now, but if we wanted to drive to a car show we could put a 3.25 in and swap in the 4.33s if we plan to race. Its just a peg leg in good shape. 28 spline like the 3.00.

How is the pinion to ring gear size come out as far as size ratio and mesh? A 3.00 seems to have a small pinion, and a 3.25 from memory seems to be a good robust ring and pinion.

Any opinions? I have both. I don't really want a 3.50 or a 3.70 on a highway trip, and taller than 3.00 is too tall, so a 3.25 seems to make sense to have for the road and the 4.33 for running rounds. Ideas?
