I tried two copies of the Sigma 85, neither was focusing correctly.. it would be OK close up, and miss focus at long distances (or vice versa).
I replaced it with the 85 1.8. Great value, but I never fell in love with the thing. It was utilitarian, and did what I need of it, nothing more.
I replaced it with the 85L II and finally got what everyone loved about that lens.. it's really an amazing piece of glass.
That being said, it's heavy, bulky, can be slow to rack focus, and costs quite a bit. The 85 1.8 is definitely the better value. The 85L II is definitely the better lens with regard to pure image results (you may have other criteria than simply IQ).
There's also plenty of MF options out there as well. The Zeiss 85 ZE is very very good, the Samyang gets good reviews (never personally used it myself) and then you get into some of the older, quirkier glass like the FDn mount stuff, and even Jupiter-9 / Helios-40.
Lots of options out there, just depends on your needs (and budget).
