Any down sides of going Borgeson vs Firm Feel?

Not exactly apples to apples but I went with the Borgenson on my 440 B Body. I have Doug's 2" headers and the clearance is awesome. A word of warning, I bought mine through Jegs instead of Bergman and its sat on a shelf for over a year, installed it on my K member and didnt think anything about it, the box said it was an 1-1/8 sector. Several months go by and go to put my steering linkage together and it's actually an 1-1/4. Jegs said they will swap it out but I have to pay return shipping because it's been so long...So check it as soon as you get it if it's going to sit for any amount of time. The box I recieved mine in looked as if it had never been opened...so I'm not sure who is at fault.
