While I agree (at least to some extent), I just wanted to point out that the color difference is not because of CCD vs. CMOS. It's becoming some sort of myth, similar to the one about larger pixels giving lower noise (they don't, per image height).
Someone mentioned dynamic range, and that probably plays a role. However, with a modern, low noise sensor, you're free to apply a lot
of contrast in PP. But of course it takes some effort, especially if the out-of-camera image doesn't inspire you to work on it.
