I can't do full justice to why, but here goes. With 3 CCD the color filter can be superior and the CCD(s) will each get one color band each. If you research how a single CCD (color) works you can see that some splashover of light is possible.
Dive in. It's fun.

I've narrowed my search down to the Panasonic PV-GS65 w/ three 1/16" CCDs or the JVC GR-D550 which has a 1/4.5 inch single CCD with 1.33 MP.
Features and price about the same but don't know which will give the best quality picture.
