I may recommend the PlayStation VR as it is powered by a "new generation console," being the PlayStation 4. While I haven't tested the Rift or Vive (just read many good things about each headset, especially the Vive), I did enjoy my time with the PS VR. It didn't cause any motion sickness for me and was very easy to set up and use -- you basically just launch the app from the PS4. Also, the trials I played of various games in the demo disc were fun while they lasted.
What ultimately caused me to return the unit (along with the PS4) was the price. It costs $400 with no full games, and that doesn't include the price of the PS4. I also am learning that I am not as much of a gamer as I once was. With that said, it may be worth it for you since you're looking for a good VR headset and/or a new gaming console. Por que no los dos?
