gooseneck adapter vs B&W companion. ride improvement???

I just bought a convert-a-ball which has cushioning built into the adapter. Works great. $600. Contacting frame manufacturers is pretty much useless. They dont want to say one way or another because of liability. Just watch the pin box. If you begin to notice any issues you can deal with them accordingly. Have the same pop-up ball as you.
My ride is smooth and feels nice.
