It would be interesting to hear how yu feel the Vive compares with the Rift.
I have both here are my impressions.
1. Rift is a lot lighter than the vive which makes long play sessions more comfortable.
2. Rift has less screen door effect than vive approximately 50% less noticeable.
3. Rifts screen isn't as bright as the vives.
4. Rifts lenses have a distortion around the edges you get a fish eye effect vive doesn't.
5. Rifts fov is narrower the lenses are squarer where as the vive is more oval.
6. Rifts touch controllers are better than the vive wands, they are more ergonomic and the joysticks are a lot nicer to use than the wands trackpads.
7. Rifts 2 sensors mean front facing only, as soon as you turn around you get tracking drop outs, vive tracking is 360 with no blind spots.
8. Rifts asw is superior to vives asw we were able to run 1.5 SS and everything was still judder free on the vive 1.3 SS was the max before judder.
Conclusion. I was very impressed with the rift it's light, comfortable to wear, the touch controllers are excellent, asw does a cracking job of keeping everything judder free so even on a minimum spec machine it is more than playable. If I was buying a vr head set today then I would get the rift given as it's nearly half the price yet offers just as good an experience, it's just the rifts tracking when it comes to 360 degree movement that lets it down but as long as you use it in a face forward configuration it works fine.
Iam very tempting to buy a rift to use with all my driving/cockpit games the comfort factor alone makes it very appealing.
