How they compare
WankzVR and POVR belong to the same network, but they're different kinds of membership. WankzVR is a single, long-running studio: more than 1,100 VR scenes since 2016, about 100 new a year, and long scenes of around 48 minutes. Older scenes look dated, and it's all one studio's style.
POVR is a hub that brings many VR studios together under one subscription, with good headset support and free previews to try first. Some of what it offers overlaps with what studios sell directly, and the interface takes some getting used to.
