Manual Steering - Standard vs Fast Ratio?

I have a 73 Duster that was converted to Manual Steering many years ago by a previous owner. The current steering box is pretty Worn out and due rebuild or replacement. The primary use of this car is a weekend cruiser and might occasionally make a test and tune pass at the local Drag Strip.

How much of a noticeable difference in day to day driving would a Fast Ratio Box like the Flaming River or equivalent make vs the Standard?

Will it take more or less muscle for parking and such with the fast ratio? (Fewer turn but harder to turn due to ratio than standard ratio?)

Being that I have never driven a Duster with fast ratio steering, I am curious to hear from those that have and if it really made a big difference in handling and Daily Driving.
