I doubt you'll find any such reviews. Sensor design and build quality
are still the deciding factor in image quality. The only CCD versus
CMOS difference that I know of is in long exposures. High power
consumption prevents CCDs from using exposures much longer than 30
seconds in a non-cooled camera. CMOS sensors are only limited by
electrical leakage.

The most obvious sides to this question is the Nikon D70 vs Canon 10D,
both 6.x MP and both take awesome pictures. The Nikon (and all of
Nikon's line IIRC) uses a CCD sensor, the 10D (and likewise all of
Canon's line IIRC) use CMOS sensors. If there are any technological
shortcomings with either design they have already been dealt with with
additional hardware or in software since both cameras take stunning
pictures. I don't doubt on the low-level they are vastly different,
but the end result (the picture and really the only thing that matters)
is equally good.

Good Luck!

Size of sensors or camera?

The recent consumer range panasonic 3ccd camcorders are small enough.

At leat one recent camcorder (Sony PC1000) is now using CMOS instead of CCD,
and the magazine reviewers are praising the merits of CMOS (as you would
expect) with regard to better contrast handling etc. Seems to me that they
haven't checked in to the dpreview site where there's nearly always a
discussion going regarding blown highlights etc.
And if 3 sensors (3xCCD or 3xCMOS) are so good for video, why does no still
camera off this feature - size, perhaps!

Joseph,

CMOS sensors have the advantage of being able to cover a large
range of brightness levels, several orders of magnitude,
definitely much more than CCD sensors.

Only if they are of the non-integrating type, which has high noise
levels.
