Which would lend itself more to a VR headset: A perfect Metroid Prime or a perfect Halo

I am not asking which you prefer, or which you think is better quality at their best, I am asking which one you think would make a more epic experience if played with the Oculus Rift. 

Metroid Prime can have the best atmosphere in the industry but Halo has its pace and vehicles.
