While other headsets, such as the HTC Vive Cosmos Elite, outperform the Valve Index in various respects, the Index remains the greatest PC headset overall.
Valve’s VR headgear is rather pricey, however,v this is mitigated somewhat by Valve’s modular approach. You may purchase any component of the kit anytime you want.
Another key advantage of the Index is that you won’t find anything that works better with SteamVR. After all, this is the gear for which SteamVR is intended. Half-Life Alyx, probably the finest VR game ever, was created for the Index. Other SteamVR-compatible headsets will work OK, but the Index is the ultimate experience for this and numerous other titles.
It’s also worth noting that the Valve Index is a virtual reality headset with positional tracking. While the trend in VR seems to be toward inside-out tracking as the norm, the Index depends on base stations to offer precise room-scale tracking.
