I feel the image quality out of all these products - and you could toss in the Pentax as well - is going to be similar (I've shot them all). There may be some small differences, and for the very discerning, perhaps those preferences may be a factor. But the ultimate determining factor is going to be the size of your wallet, and the willingness with which you pull out the contents to trade for what you want.
Each of these products has something to offer, but the price of admission will have to be factored in on a subjective basis.
