Either the Canon or the Nikon will do you very well... giving pro's and con's of each system is nearly pointless, as it has to do with what works for YOU (kinda like the whole audio/speaker stuff - it needs to work with your ears).

Personally, I like the Canon system (samples of my work can be seen on my website Unit-One Studios, but I could get very similar results with a Nikon body... I just prefer the Canon.

I'd recommend that you go to a camera store and play with both systems... see how they feel in your hands. Go through the menus and see how they feel to you. Both systems are more than capable, but you need to get what works with you.
