Sorry i don't buy the pixel argument. Imagers know the important factor is not how many mega pixels you can cram onto a sensor but the optimal relationship between pixel size and the focal length of the scope, (see info on the Nyquist Criteria), as well as many other factors such as low noise performance, light sensitivity (QE) of the sensor etc.
People can, and do, create all sort of arguments to justify their scope choices, but the hard core aperture chasers ignore the realities of the Seeing conditions and what can be gained, or not, by increasing aperture. Bigger is not always better.
