I own a Digital Rebel and am a little dissatisfied with how ym images are coming out. The camera is great however when I want a photo that is going to be printed at an 8x10 or bigger I start not lieking the camera so much. When I compared my Raw CR2's next to Raw NEFs coming out of a D70 I notice a lot more color noise in blacks out of the 100 iso on the 350D as compared to even 320 iso on the D70 forget about color noise, the image just seems cleaner in general. Shouldn't iso 100 be cleaner no matter what the camera manufacturer is? does the problem lie in the diffrence between the raw formats of canon and nikon? The nikon seems a lot sharper but perhaps that is due to a better lens being used.
 
It's tough to make a comparison like this unless you use both cameras to shoot the same subject, with the same lens, at the same time, and use the same raw workflow. That seems odd, because Canon has areputation for using a much more agressive in-camera noise reduction. Now the D70 has a CCD sensor and the 350D has a CMOS sensor, so you may be seeeing some of the noise more inherent for a CMOS. But again, it's hard to know if the comparison is really valid.
 
I've used both extensively and I can tell you 100% that the Canon should not have more noise than the Nikon. It might be good to have your camera checked out if you are getting extensive noise. What are you using to uncompress your RAW files?
As far as sharpness, it does indeed depend on the lens you are using. I just bought the Canon 100mm 2.8 macro lens, and I have to say, this is by far one of the sharpest lenses I have ever used, canon or nikon. I'ts really quite disturbing just how much detail can be picked up with this lens.

If you would like, take a look at my website, quite a few of the photos on there are taken with either a canon 350D or 20D, both of which create identical images.
 
Lets try this...I uploaded two raw files, one from the nikon at 400 iso and the other from the digital rebel xt at 200 iso. granted the digital rebel picture is darker, look at the mans face in the picture and how noisy and unsmooth the colors look. try to compare this to the dark shdws int eh nikon photo. it just seems like teh rebels image starts falling apart when there are shadows to hold on to. I understand that the dynamic range might not be good enough to expose for the shadows as well but that doesn't mean it should look so grainy in the blacks.

Here is the main issue of while you are seeing grain on the photo. I took a look at both of the files, and the settings that you used on them. The best thing to look at is the exposure slider. Your exposure slider on the nikon is set at -1.75 where as your canon exposure is set to +.10. This will immediatly introduce grain. These photos are way too different to be compared. The nikon is shot with a flash, the canon is shot without a flash thus needing added exposure compensation, since the shot is clearly under exposed. Since the nikon is shot with a flash you could bring down the exposure level quite a bit eliminating any kind of grain. I guarantee you if you light a scene and shoot it with both the nikon and the canon, the results would not be as night and day as you see here. Both cameras handle grain very well, with canon usually having a slight lead especially in higher ISO's. Also if each is shot with a similarly sharp lens the Canon will have more resolution. The D80 on the other hand seems like it should be a great competator for the new Rebel XTI, both being 10MP cameras.
 
I think they are close in performance. Lenses will make the difference. For me, the size of the camera was important. Big hands go better with the Nikon (okay, start with the "Big Hands" jokes).

I have a couple of shots with the D70 on my website (see link below). I have a friend who shoots with the Canon and they look great.
