In my experience, I'll agree the 5DIII worked better for wide aperture and fast action than the Multicam3500 at the exterior points. Having the better spread out points is definitely something you have to try out for yourself in the real world, Maiaibing. It helps tremendously with compelling composition.

To be honest, I haven't seen any reliable comparisons online that are conclusive, one way or the other. As I stated before, I tested them head to head, personally (in part because there was nothing conclusive online). I didn't write up my results as a white paper or a blog, and have no intention of doing so. You may conclude whatever you wish.
Fact-based discussion? The facts are (as one of your links pointed out) that the 5DIII AF is better spec'd, with the exception of number of AF points available with an f/8 TC combo. The 5DIII has more AF points, more cross-type points, cross-type points spread across the frame instead of clustered in the center, and central points with a wider baseline (f/2.8, five dual-cross points) for increased accuracy.
