Just to add to it...your choice may also depend on the editing software you decide to use...if any.
The Sony is supported by more pro and semi-pro editing software of the bat without any need to do any converting.
Camera wise a lot of people once they try the HD7 like the semi-pro feel where as the SR8 seem more suited to the home/family/holiday crowd.
Also both companies have new cameras coming on line in the next few months and it might be wise to wait not only for price drops in the two models you are interested in but also to see if the new cameras have any extra features you like.
CMOS tend to use less power, so the battery should last longer than on a CCD cam
1 CMOS/CCD should be better in low light than 3 (for a same sized sensor). Single sensors tend to be larger than those on a 3 sensor cam.
3 CMOS/CCD's gives better colour balance in good light conditions than a single sensor cam
TBH, you wouldn't normally notice which of these you were using. My HV10 had a CMOS, so did my Sony HDR-HC1e but my Panasonic SDR-S150 and HDC-SD7, and HDC-SD9 all have 3CCDs.
