Borgeson or Firm Feel steering?

On my 69 Dart resto. Since I am replacing the steering box, the old one is leaking and has play in it, should I go with Borgeson or Firm Feel? I know the Borgeson is smaller and lighter. Other than the column steering rod modification is there anything else I need to watch for? Is the header clearance better? I have Firm Feel in my 69 Sport Satellite convert and it's been great.

I have the K-frame out and will re-enforce with some extra welding that I've seen in other posts.
What are your thoughts?
