Post Touch it comes down a bunch of other things because you can get either and not regret it.
* The Vive tracking system has more usable range, but that doesn't mean anything for > 80% of spaces.
* Touch controllers are much better than the Vive wands (pick your reasons).
* Oculus USB requirements are a disaster as is the USB extension situation.
* Oculus can run four sensors with fewer occlusion issues, and yes I still have occlusion with 4 sensors.
* Optically you find people on either side in terms of which is better. Without double blind testing several samples of each I wouldn't assume anything.
* I'm not sure if they have parity for reprojection performance
* Vive has the passthrough camera which seems to be poorly utilized.
* Oculus comes with built-in headphones, that's 100$ add on for the Vive.
* Rift doesn't come with a third camera that's a 60$ add on.
* Rift was lighter, but newer Vive units have gone on a diet bringing them closer.
* Vive has a longer cable and if you have a primo space like mine it's a big deal. You need a biiig space though.
The Vive is more expensive right now. Optically I think the Rift is better, and it's dirt cheap to add prescription lenses to (<30$). The Rift works with Oculus Home without hacks, but the reverse is not true of the Vive.
