I found the MD 85/2 about as sharp as the Sony 2.8/85 SAM and Tamron SP 90/2.5. None of these was as sharp as a Canon EF 85mm F1.8 USM. The SAM lens seems very similar to the Contax G and C/Y Sonnars mentioned above.
My favorite 85mm is the Tamron SP 85mm F1.8 USD from 2017. It may not be the sharpest 85mm.
