Any down sides of going Borgeson vs Firm Feel?

I'm going through the steering/front suspension right now on the Challenger. Since I bought the car as a shell, I have no idea what the power steering box condition is, and I don't feel like risking taking it back out after the engine is back in. So, I looked into Firm Feel at a cost of $425, but add shipping in, and probably another $100. At that point I am close to a Borgeson unit at Summit pricing. It seems like a no brainer, to spend the little extra and get a little better ratio,plus more header clearance. The car is not numbers matching, so that is the only reason I could think of keeping it. Any input would be appreciated from those who have the Borgeson as well.
