That entirely depends who you ask and what glasses is he wearing 
From gamer perspective if you look at the top rated VR games in Steam starting with TOP-10, 9 out of 10 are made with Unity and the one exception is Pool Nation being UE4. I don’t know if there is even any other titles made with it in the TOP-100 except the ones I have, Raw Data and Brookhaven which are both below 90% rating due various problems.
For CryEngine there is only one known VR game for current generation devices, The Climb?
