I always give this advice when considering a VR headset - If it's good for games, it's bad for porn and vice-versa.
For porn you don't want to be tethered, and you don't need bells and whistles that make gaming better. You want light-weight, and you want to avoid neck strain (looking down a lot can be a pain in the neck, with a heavier headset, it gets much worse).
I haven't gotten a new headset in a long time, but when I did, my porn headset was PVR.fun . I suspect it's still the best for porn, as that's what it is built to do.
I have pre-ordered the Quest 2 from Oculus. That'll be my gaming headset some day, and I'm sure I'll post about how it does for porn...
