The Borgeson box is a faster ratio than a stock mopar box, but is not as fast as the fast ratio arms.
The big advantages to using this box is lighter weight, 12 pounds total, less space, slightly smaller than stock, and higher precision. Is that worth it for the price tag, that depends. Firm Feel rebuilds stock boxes. In some poepls minds you cannot greatly improve the precision of the mopar box even though you can change the assist it provides. In this regard, the Borgeson may provide a more precise on center feel to make it seem almost like a R&P set up. Borgeson makes the steering boxes that are used in a number of late model vehicles which, I'd bet, any number of people may think are R&P equiped. So it is a very precision piece. To fit it to a classic mopar, they need to modify the housing and mounts to match the mopar dimensions, so it has alterations and welding on the box. To some this is a big negative regardless of feel.
So, it kind of comes down to personal preference and pocketbook.
