All these lenses show nothing but excellent sharpness at f5.6. If you really want to split hairs, you may see the MC Rokkor 2.5 100mm a very tiny little bit behind the other three lenses, but nothing that matters in any way in practical situations.
I see the MD Rokkor 2 85 in front concerning pure sharpness very, very closely followed by the MC Rokkor 1.7 85mm, both really excellent. The MC Rokkor 2.5 100mm holds the third place and the Macro Rokkor comes in last but also it is used wide open here.
Wide open (without the Macro lens):
Here the MC Rokkor 2.5 100mm is the leader, showing very good sharpness even wide open. Place two goes to the MD Rokkor 2 85mm and the last place to the MC Rokkor 1.7 85mm. I would rate the 2.5 100mm the only lens I can use wide open if critical sharpness is required. But with the two 85 lenses you can easily stop down to f2.8 and get even sharper images. And lets take a look at the MC 1.7 image wide open: A creamy look like no other in many cases perfect for potraits and a exceptionally sharp lens stopped down too.
So my most used (and loved) lens in this range was and remains the MC Rokkor 1:1.7 85mm.
The Macro too shows exccellent results for real macro work where I usally at least stop down to f5.6 or f8
and is still my favorite lens here.
