I have both the Oculus Rift and PSVR. Games like Resident Evil 7, Eve Valkrie, Lucky's Tale, Arkham VR, Rush of Blood, Battle Zone, VR Worlds, and VR Playroom are amazing in VR as well as flying an x-wing in Battlefront which has a VR experience. Lucky's Tale is only available on Oculus Rift but it is an amazing game. I have watched some amazing VR videos on an app called Within where it feels like you are sitting in the audience on a Saturday Night Live Q and A with Jerry Seinfeld hosting. That was pretty good. As well as flying over Los Vegas looking down from a helicopter on Hulu which I did that on the Rift. VR is going to be great when it takes off.
As far as porn goes, its amazing. My personal favorite video is with Mia Malkova at Naughty America where she is playing host at a New Year's Eve party and you are her special guest. She gives you a tour of the place and then her and 3 other girls start having sex with you. Another scene I liked was you are at a beach and you feel like you really are there. There is this girl talking to you leading up to a porn scene but I was really mostly interested at being at the freaking beach with the waves rushing in at your feet. That was really awesome. Hologirls had a scene with Bree Daniels which I really liked. Wankz VR has a fun christmas scene called Santa's Wankshop which was pretty funny. Reality Lovers has a scene with Linda Sweet if you like her or redheads in general.
I love both my VR headsets and not disappointed in getting either one. PSVR is great for games and Rift is great for porn and videos. I got a good deal before Christmas on a Cyberpower PC that came with the Rift for a thousand dollars. There are deals out there just look around.
