Degrees of freedom: The Quest has the advantage of a six degrees of freedom tracking system (6DoF), while the Go had only three (3DoF). 6DoF devices can track more than just your head movements, they can keep track of your position in a room as well. This just makes for a better, more immersive VR experience. Behind the scenes: The Oculus Go was the first VR headset that you didn’t need to connect to a powerful PC (like the Oculus Rift) or a mobile phone (like the Gear VR). We’re basically seeing a shift to more capable standalone headsets like this. As The Verge notes, phone-based VR is all but dead. The future: If you have a Go already, Oculus says it will maintain the system software with bug fixes and security updates through 2022. No new Go apps are being accepted, and the Go app store will stop getting currently developed apps as of December 2020. Bottom line: Now if you want to get into Oculus VR, you’ll need to spend more on the Quest, which is admittedly a better device overall. That is, if you can find one.
