My personal experience/opinion: The 6D works good in critally light conditions, the 5D3s AF is superior.
Visited an workshop in Munich´s zoo. Compared the shots with the 8 other fotographers (4x6D, 5x7D, 4x5D3. Mostly 100-400mm, 300mm2.8+2x, 1x 400mm, 1x500mm):
5D3 was superior, shooting the fast flying hawks and milans. Sharp pictures: 6D ~50%, 7D~75, 5D3 ~80-90%.
But when we shot swimming sea lions (dark objects), the AF of the 6D could (nearly) reach the 5D3s. And the details of the black and dark brown lion pelts were as good as the 5D3s.
An good lens helps the AF of the 6D @ moving objects more than if you use it on the 7D. Using the outer AF points in moving objects, is a clear point of the 5D3 or 7D.
