Blind tests has shown that there is nothing about Canon that makes their images unique. At this moment Sonys sensors has higher DR, higher color sensitivity and better low light performance. In the past Canon had better colors but all this 'Canon color science' is no longer valid. Just like that nonsense about 'film look' (24hz) needs to die sooner or later (which it will).

Where can I buy a camera body with that APS-C sensor? Vaporware! Or that 120 mpix APS-H sensor they repeatedly mentioned through the years but still is nowhere to be found in the wild? Vaporware! No, Sonys is just about untouchable when it comes to sensor tech. The reason is that they earn a LOT of money selling all kinds of sensors (in particular mobile sensors) and so they can afford to spend much more on R&D than both Nikon and Canon. Canon did a great job with the sensor in 1DX II and 5DIV. But they are still way behind and I don't see them being able to compete on sensor tech now and in the future.

It has been demonstrated again and again that there are just about NO advantage to bigger pixels except readout speed. 100 mpix is fine, just allow for downsampled raws in the final camera body (like Canon does). I'm currently using two bodies with 24 mpix (A9) and 42 mpix (A7RIII). 24 mpix images are less 'crop'-able. But even 42 mpix is not enough in some situations. So I'd love a +100 mpix sensor! Diffraction? Yes of course. The laws of physics cannot be broken But if you shoot mostly f/4 or wider like most sports/wildlife/portrait people then diffraction at f/5.6 is not an issue. Even with some diffraction a 100 mpix final image would never be less sharp in print/display than if taken with a 42 mpix sensor (and the same lens/setup).
