It comes down to price and budget of course, but I still think that the 1DsIII is the most ideal camera on the market. I was "only" able to afford the 5DII but I would chose the 1DsIII over any of the others, including the 5DIII and the 1Dx. I still don't see how the 1Dx is an "upgrade" from the previous top shelf pro model.
