I'll be fair here as well, and say both are great cameras. I also agree it is the glass that counts, and not the camera, and the application of your photographs is very important. I would not recommend the same camera to a sports shooter as I would a wedding photographer, nor would I recommend the same camera to a location porn photographer as I would a studio fashion photographer.
That being said, my prefernce is Canon ALL THE WAY. Their leaps in digital technology have been two steps ahead of Nikon since the beginning; bigger chips, more megapixels, better features, and cleaner bodies for less money than Nikon. I also like that I can control my Canon very intuitively with ONE HAND; holding Nikon I feel like I have to play a fucking trumpet to change any settings.
Also, just as an aside, I went to one of the top photography schools in the world, and most (maybe 70%) of the future professionals there switched their entire system from Nikon to Canon when they went Digital.
Either system is fine. I have my prefernce. It is about how the camera feels in your hand; how natural it feels to use it. It sounds stupid, but the first time I felt a Nikon, nothing happened. The first time I held a Canon, I swear I felt a little magic happen.
