AFAIK, there are 6 variants of CZ 1.4/85 T* - AEG, AEJ, MMG, MMJ, Contax N and the present Zeiss ZF, ZF2, ZM, ZK, ZE. All have different characteristics. The MMG and Contax N are quite hard to come by. Only the MMJ, Contax N and Zeiss can still be serviced by Kyocera. The Nikkor AI-S 85mm have CRC so has the closest MFD.
As what others mentioned, there is also the Samyang 85/1.4 To make it more fun, there is also the Pentax 85/1.4, Leica Summilux 80/1.4. Have fun deciding which you want.
Solely on the Nikkor vs CZ, I do not have the former but I read that it is soft at f1.4 and f2. The CZ is sharp from f2 onwards.
P/s: remember to add in mount conversion cost into your consideration such as the ones from Leitax.
