The HP Reverb G2 is easily one of the best VR headsets out there thanks to its incredibly high-resolution lenses, which all but eliminate the screen door effect and really help with immersion. It doesn’t quite have the accuracy of the Valve Index or HTC Vive Pro, but it’s cheaper and easier to set up than both.
No screen door effect; Very immersive; Easy to set up; Not the most expensive…;
...but not the cheapest, either; Motion tracking lacks precision; Cable gets in way when not in use
