Comparing cameras is always very difficult and the outcome will strongly depend on the application. My personal strategy is always to rather rely on own data than what was written in product brochures or papers. Thus if you get better images with an EM CCD camera this is the camera of choice.

I tested an PCO.edge sCMOS camera (no commercial interest) on the new Yokogawa W1 spinning disk head and I was really impressed. For me the main advantage of this type of camera is the large field of view in combination with the high acquisition speed. Also the small pixel is a plus as it allows imaging under nyquist conditions (or even doing oversampling) with low magnification objectives having a high NA. Nevertheless at low light application I prefer using a back illuminated EM CCD camera.

And on a conventional spinning disk system it is at least questionable whether a sCMOS camera is the best camera, as large areas of the chip remain unused.
