Funny you should ask. I have been tracking this stuff:
ADVANTAGES:
CMOS
Fewer ancillary chips
Higher speed
Lower supply voltage
CCD
Better uniformity (from one pixel to another)
Better Dynamic range
Requires less silicon per pixel
Lower noise
Better anti-blooming characteristics
Better responsivity (Quantum Efficiency)
Better fill factor (less space between pixels)
Lower sensor complexity
DISADVANTAGES:
CMOS
Require post-processing circuitry to compensate for noise
CCD
Higher system complexity
