There is pretty much nothing to add. The 85 1.2 II is way slower in focussing than the 50 1.2L, but the 50 1.4 is even faster, so i wouldn't say the 50 1.2 is a quick focussing lens. When it comes to sharpness wide open than the 85 is wayyyy sharper. Both have little issues with CA's at 1.2 in high contrast szenarios but thats normal for such huge glasses i'd say. Another thing is, that the full electronic focus of the 85 is kind of weird. You have to switch to "manual focus" if you want to focus manually, there is no override in AF mode. The focus ring is more like a "sensor" that gives the information to the focus motor. This doesen't work when AF is enabled. The focus ring is also wayyy to smoth, it turns like its a spinning wheel. I like the "mechanical" way of the 50 much much better. Another thing is that the 85 is not weather sealed and the front element extends (and sticks out) a lot when focussing (the front element of the 50 also moves, but it dosent stick out of the lens at any focussing distance). If I could only afford one it, would defenitly be the 85 1.2 II because of its simply the best portrait lens out there (if you are kind of close to your subject, sometimes I take it also for whole body portraits). If you want more "distance" to your model and en even tighter field of view then go for the 135L.
