I myself have not noticed any drag on the machined Ti (or SS for that matter) Blackbird either, but have not tried the polished, to be fair. There is a cosmetic difference, of course, if that is important.
I've got a polished SS BB SB, and have had a machined BB. If there is a perceptible difference in 'drag', I was never able to perceive it. Same with other DEs IME. Just a matter of aesthetics from my point of view. Polished is prettier.
