Canon Pro 1 - Canon Rebel - Nikon 8800

You cannot go wrong on any of these.

If you are into action and/or low light photography I would lean toward the Rebel.

I think Nikon has bested the Canon Pro 1 with their 8800.

Here is a side-by-side comparison:

Notice the red stars - this is the owners overall rating of the cameras. Looks equal to me.

Just below the red stars is a link to the "owners opinions". Straight from the horses mouth.
