I don't know that either has to "win." Oculus games clearly replace the hardcore FPS/Computer game sort of market, whereas Glass games are more a replacement for cell phone games, more casual things, or real-life MMOs/ARGs (which there hasn't really been a market for before, except maybe Ingress and a few others). I see both being pretty popular with gamers (although I guess the stereotypical ones who just sit at home all the time won't necessarily enjoy ARGs).

With gamers? Oculus, by a landslide.

Glass can enable some interesting layers over the real world (I'm personally looking forward to Ingress on Glass), but it isn't even close to the level of immersion the Rift offers.

There's room for both, of course. Initially I expect Glass and AR devices to be more palatable to the general public than VR.
