Canon v. Nikon is just like Coke or Pepsi, Ford or Chevy, etc. You're never going to get a straight answer. I personally went with a Nikon D40. It felt the best in my hands compared to the Canon. Plus a good buddy has Nikon gear, so we can swap lenses which means I have free access to even more equipment.
My suggestion is to go to a store and hold them in your hands and pick the one that feels "right". They will all take great pictures and you'll be the limiting factor, not the camera itself (at least for a while).
