I had the 85L for about 1 year, but sold it for several reasons, for this price you get :
Disadvantages :- CA (just like the 85 1.8)
- slow AF (85 1.8 a lot faster)
- heavy (85 1.8 a lot lighter)
- your wallet is empty (vs you have money left or 2 lenses)
- in tests (see other topics) bokeh is +- the same,difference not 5x better
Advantages:- better contrast/colours (I pp all my pics anyway, so in 1 click sorted)
- better lowlight out of hand
- 1.2 is a sexy heavy bulky lens (1.8 looks like a cheap kitlens)
I had the L for about 1 year and I shot almost always wide open (that's where you pay for), mostly 1 eye sharp as the dof is so thin, or only eyelashes sharp,...
I found the f1.8 more comfortable seen that you have immediately more chance to have 2 eyes sharp wide open.
As both lenses have CA I got tired of the purples (even if it's correctable) I sold the 1.8 for the 135L.
I got this 135L a second time, it's the perfect lens of the 3, supersharp wide open, superbokeh (not f1.2 or f1.8 but very close as the 135mm thanks to the longer focal distance) and a middle price.
You just need to use it more to appreciate it, even if it's a bit longer, then you get the wow pics of our famous model/wedding photographer Dankata
Some don't like the 135L bokeh as they find it more a studiolook as you nuke the background, but this all in relation with the distance and at f2.8 you have different and even more razorsharp look.
I recently talked to a modelphotographer, he said he uses his 85L only at f2.8 to have more sharpness... this says enough for me...
I think I will buy the 85 1.8 again as a compact extra lens for travelling,... it has great value.
Just like I keep my 135L on top of my 70-200 2.8LII, some would say it's both are redundant when you have 70-200 II, but they are a lot more compact and lighter for travelling,...
First I saw 85L as a real luxury lens seen the price and impressive heavyness when you attach it.
Maybe you can buy it like I do, next year you can re-sell it for the same price, you hire it for free actually

So after testing myself, both 135L & 85 1.8 are the best portrait primes for me.
