I agree that the quest 3 is the obvious choice for porn at the moment but it's actually really crazy (and a little sad) that the quest 3 is the best option in pretty much any price range right now. However that won't continue forever for the mid / high end price point.
I do think the future for consumer vr is wireless but I also think you will get more pc VR streaming at some point. Maybe something like the deckard or another pc vr headset. Standalone is okay for video but standalone is pretty much useless (imo) for anything else due to the huge performance limitations (excluding maybe the avp).
Anyways, seems like a real shame to neglect steam vr, especially long term
