6D Dynamic Range

I would suggest you base your decision on feel ,usability, and lens selection more than DR. The recent QC issues at Nikon are also quite problematic to me. I think all this buzz about the need for 14 stops DR is generally speaking the biggest bunch of BS since "nobody needs more than 6 mega pixels". Pulling shadows is almost always done as a last resort to rescue an image and if you look at the examples on the web you will see that most people would discard the scene even after post processing. If you want a drab boring uninteresting image make one with 14 stops of DR. A valuable lesson I learned from famed Nikon shooter Moose Peterson is to INCREASE the blacks, not turn them into a muddy grey! If you see any of Moose's videos the FIRST thing he does in post is bump the black level...sometimes more than once. He says his secret to "sharp" pics is a high black level, it increases contrast and the appearance of sharpness. If you look at the most famous Nikon shooter Joe McNally's work it almost always has mostly dark dramatic shadows with a central subject well lit. Those guys are not bring up shadow detail they are reducing it. Take a look at Moose Peterson's gallery shot of the grand canyon on the front page of his blog at the link below and tell me how much he lightened the shadows....do you think that shot is 14 stops
