With VR you see the girls in real size, a few centimeters of you and 3D. You can see the pores of their skin, details you can't see on an flat screen. They look REAL, almost the real thing (with good glasses). It is a revolution. And 99% of VR movies are POV.
HP Reverb G2, Valve Index, Pimax have more resolution, but they are expensive. The best cheap option is Oculus Quest 2. Don't use a smartphone, they are not good for VR.
