Roomscale is apparently killer:
If you have the space for it, for my money, the HTC Vive blows the Oculus out the water as a long term investment.Link
Room scale VR is amazing, but does ideally need you to make space in your life to accommodate it. Having a Holodeck in your home doesn't come without it's drawbacks.
VR is here, and I have been sold as a believer. While the Oculus is a very strong VR headset, the Vive feels like it's in a league of its own comparatively. The big sticking issue is how the market reacts to the price long term, and if development of new games maintains a consistent pace.
