This is assuming you are running stock sized tires on each car.
For gas milage considerations, here is a break down top gear RPM at various cruiseing speeds on the highway.

And for full throttle acceleration considerations, here is a break down of what speed you are going at the top of each gear just befor shifting to the next higher gear (assuming shifting at stock redline of 7,000 RPM) and what RPM you enter the next higher gear at.
