Everyone keeps talking about the same 5 studios/networks. However, I recently discovered some lesser-known studios that appeal to me much more in terms of variety or the intimacy of the scenes than the big (US) studios.
For example, I think that VRHush has taken an extremely good development especially in the last months and with the standing missionary positions and some interesting camera work, they bring new excitement into the somewhat stale world of VR porn.
VRSins is also an interesting studio with similar fresh direction - although I find the download limits and re-releases with faked release dates on the official website somewhat questionable and therefore have to refrain from direct support so far.
What are your hidden gems?
