I shoot Canon, always have, but have shot with friends' Nikons and liked that as well. I do like the Nikon quality, but the camera felt more simple to me...not that it's a bad thing. It's almost like PC vs. MAC, Canon being PC. I can do more with it, have many more options if I choose to have them, but the Nikon, like MAC, is more simple, and it just does the job and it does it well. It's all a matter of taste. Whenever I pull my Canons out I get huge compliments....MAN LOOK AT THAT CAMERA! they see the 5D with a 70-200L white lens with red ring and it just blows their mind. They see my friend with a Nikon and have not really commented. Someone above mentioned the Nikons looking more aerodynamic...well, if we were throwing them out a window, I guess we could conisder that. I also don't like shiny buttons and things of that nature. I like the all black look, very classy and sleek. And to me, the body size of the Nikon doesn't seem to change much. There isn't an awe factor like there is with Canon. Again, they are both great and I have shot with both but in the end I take Canon. I have thought about switching to Nikon but have too much invested in Canon. I will buy some Nikon down the road to toy around with for fun maybe, like a D90, whatever.
