Cameras are not really "sharper" than one another, the possible sole exception to that being cameras like the D800E with the AA filter negated, and even then you can process an image to look pretty well the same. The lens, processing, etc. all make it so that any camera can pretty well be as "sharp" as any other, if you want to think of it like that.

Canon uses higher default sharpening than Nikon, so when you look at JPEGs, Canon usually has sharper out of camera JPEGS, but all you would need to do is go into the menu and turn up sharpening a few ticks on the Nikon, and they would be the same. Shooting RAW, the only differences in sharpness would be with lenses, technique, and post processing - little to do with the camera itself.
