I personally love playing him in both lanes. I've played more adc than mid, but I found him strong in both. I successfully played him against Zed and Vel'koz, and his traps gave me the escape I needed from ganks most of the time.
to answer the question. Jhin adc is most viable, yes I have played him mid too, but he does just get destroyed from assassins and ganked pretty easily. Jhin ADC is a must
Mid - Pretty good but easily punished with Assassins / Long / Burst / Poke Mages
Jhin as mid can help gank side lanes with long range of W/R though
And E does provide good control of visions
