sogman used the 8kx for the longest time and that had an amazing FOV. That truly massive fov was amazing for porn even though it was blurry on the edges. At some point though video quality became greater then those displays can handle. Now I don't think it's a good tradeoff anymore.
As for the newer pimax headsets like the crystal. They state a massive fov but they aren't nearly as massive as they say (Pimax hugely inflates their fov in their marketing). It's more similar to index level FOV which makes sense when you cosider that the crystal has the exact same amount of pixels as the 8kx. You can't have the same pixel while increasing quality and remaining the same FOV.
Still their FOV is bigger then quest and the headset has much better screens. That's nice of course. The upcomming super will increase that by a lot again. All though that will need truly next gen video quality to be an advantage for porn over the crystal I suspect. Then there are these announced headsets that don't seem real yet so I don't really consider them as such with their track record.
Anyways, I wouldn't buy an 8kx at this day and age. Hope a better next gen high fov headset will come along though. Technically the somnium vr 1 fits this bill somewhat but it's too expensive for what it is imo.
