NTRUEncrypt or other quantum encryption????

I see in talks NTRUEncrypt may used in future in some parts....

Why not Ring-LWE key exchange or supersingular isogeny Diffie-Hellman?? for forward secrecy support....ntruencrypt doesn't support as i know? is it not compatible for parts or planned or something else??

sorry, forgive me i am not a professional....only interested.
