Consider this, you are shooting a subject at a distance of 5 feet with an 85mm lens at f/1.2.
To be fair, the f1.2 dof is a challenge for any existing Canon af system because even the 5d3/1dx af points aren't spread far enough so there is no need to recompose, and this thin dof beats any phase af precision... learning to manually focus on the lens or moving the camera is a good idea, at least with macro shots I know it beats trying to phase af.
I've owned the 85L for a grand 3 days now and so far, I've found it to work pretty accurately on the 5D3. I'd guess the focusing would be even better on the 1DX.
It's a challenge on the 6D though and I'd like to use a tripod and live view for shooting with this lens.
I'll do some test shots with both bodies and post the results.

When it comes to gear, it is better to vote with your wallet. Bitching on online forums like a lunatic doesn't get you anywhere!
