The "fine detail" and "color" rendering is what I see differentiating the CCD's in the M8 and DMR and the Cmos in the 5D. The way that translates (for me) in actual prints: the CCD offers (to my eye) a more "traditional" photographic look in the print; the Cmos offers (to my eye) a smoother "digital" (some say plastic) look in the print. Obviously these are subjective calls.
