50mm f1.4 ART (especially on Canon)

Greetings,  I'm a 5Div and 5Ds user potentially moving from the Canon 50mm f1.4 to either the Canon 50mm f1.2L or the Sigma 50mm f1.4 "ART".  I've never owned a 3rd party lens before but I'm intrigued by the Sigma 50mm art lens despite it's massive size.

I was looking strongly at the Canon 1.2L but from what I've researched so far it seems it's mostly a sort-of "cult" lens.  People after that extra .2 of a stop of bokeh.  The results I've seen the bokeh is unique but overall the lens is way less sharp than the Sigma Art at all stops (maybe equal at f8).

But I'm also reading that the Sigma 50mm Art had / has issues with focusing problems  / consistency.  It's tack sharp when it's in focus.  There are many reports of people having issues especially with back-lit situations.

So my question is, between firmware upgrades, employing that Sigma USB puck calibrator and in-camera micro-adjustment, how is this lens fairing in 2018 with regards to it's focus problems?

And if calibration works, can I calibrate to 2 camera bodies to it?

Thanks!
