The only metric I go by is keepers when I get home on my computer, and so far yes, the 5D3 and 1D4 have had a fair share of misses, but the 1DX I have had absolutely no misses.
Aye. I've heard the same thing from all the camera reviewers as well, including those who have historically been die-hard Nikon users: The 1D X AF system is unbeatable.
Even in the bird and wildlife photography arena, which is admittedly a lot smaller, both Canon and Nikon users have raved about the 1D X AF system. I've even read a couple reviews that indicate the 1D X's facial recognition works with animals and birds, often in profile. O_o As bird photographer myself, I'd LOVE to get my hands on a 1D X, but as I don't make much money off of my photography, its really hard to justify the $7000 expenditure (especially on top of the $10k+ glass I'd need to go along with it.)

I don't owe you any evidence, because I really don't give a crap what you think, honestly. All I know is that I have a pair of 1DX's, I'm making money, and I'm not having any misses. I'm happy. Are you?
