Clients don't care about MTF. They care about the image. It is funny, about 100 years ago only 4x5 was the acceptable format for journalism "because of its quality" and the smaller formats were just rejected out of hand. If an art is simply based on technical criteria, then it is no longer art. Edward Weston was rejected for an exhibition by the Royal Photographic Society because his work did not have enough "shadow detail."
But you MTF argument is false. A smaller format at a given aperture will actually have better MTF over the image simply because of greater DoF. Unless you are simply photographing flat planes, then MTF is not a reason for buying anything. Also, MTF is dependent on pixel pitch, so an RX1R will have exactly the same MTF as many 40MP MFD sensors like those from Phase One, Pentax, and Leica.
I buy cameras I enjoy using. That is about as complicated as it gets.
