-According to the Specs Canon's 1D has a bit more noise, but i'd say it beat the D3s simply because of pricing.
-Video is "eh" not really interested in that attribute of both cameras.
-AND of course of the fps on the Canon, for ME is a thumbs up.
Just wanted to share.
In conclusion Canon K.O.'s the Nikon in my opinion.
Be EZ boppers.
