HTC Vive/SteamVR

HTC's Vive is a comprehensive package that includes a headset, two motion controllers, and two base stations for defining a "whole-room" VR area. It's technically impressive, and is the only VR system that tracks your movements in a 10-foot cube instead of from your seat. It also includes a set of motion controllers more advanced than the PlayStation Move. But that $800 price tag is pretty hard to get past, and PC-tethered VR systems like the Vive need plenty of power, with HTC recommending at least an Intel Core i5-4590 CPU and a GeForce GTX 970 GPU.

Oculus Rift

The Oculus Rift has become synonymous with VR, even if the brand has lost some of its luster against the HTC Vive and the PlayStation VR. The retail version of Oculus Rift is out, and while it's more expensive than the developer kits were, it's also much more advanced. From a technical standpoint, the headset is nearly identical to the Vive. It costs $200 less than the Vive as well, but it lacks the Vive's whole-room VR, and if you want motion controls you'll need to spend that $200 for the (admittedly excellent) Oculus controllers.
