Coin toss.

It isn't so much about the camera as it is about seeing the shots. If you have too much gear to choose from, you'll busy your mind with thinking about what camera or lens to use, which in my opinion is counterproductive. My best results always come from sticking one lens on one camera, and force myself to work with what I've got. It allows me to let my imagination work full time, and to be ready when the moment approaches.
