Sorry if it came across like it, I didn't mean to accuse you of snake oil pandering. I just read the article and I think you misremembered, the article states CMOS has in fact a significantly lower noise floor (I wondered about this, because I remember when the next gen CMOS sensors came out in the pentax K5 and the Nikon D400(?) it was possible to push the shadows so strongly that you could essentially take a completely black photo and push it up to the same as if you would have taken with higher ISO). CCDs have a "more pleasing/film-like" nonlinearity, but I believe if you shoot raw a linear response is always better, because it gives you more flexibility for post processing.
