Both backs are cooled, so that may reduce the relevance for
out-and-about still photography, but the main thing is that the CCD
back is better at capturing fine detail and requires slightly less
colour correction.  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.
