There's a few different VR systems other than Occulus. Like I mentioned, Valve has the Index which is a really good headset but it's pricy and needs a pricy gaming PC. Sony has the PSVR headset for the PS4 (I think it works with the PS5 too). It's along the line of the original Quest for quality. HTC also has the Vive headsets but they're up there in price. I think they're supposed to be really good but I don't know anyone with one due to the price.
