The CMOS back has some advantages in edge separation of low-contrast edges, but tends to produce a very smooth looking image because of the slight loss of fine detail. I think they are on about par in terms of noise. A multi-pass scanning back is better than both of them, but isn't practical for things that move or where you do not want to illuminate or otherwise bombard the sample with radiation (light, electrons, whatever) for long. These differences may reflect these sensors rather than their types as a whole; in regular photography I'm never going to be able to buy a dSLR of the same model with both sensor types to find out, I suspect.
