Which benefits do you gain from buying the Chinese Vive Pro or Pro 2 instead of the superior Valve Index? - asking since you already have a Quest 2 for PCVR. I was underwhelmed by the mediocre performance, short durability and abysmal support on my HTC Vive Pro. Source: about 1 year ago

Also, you could get a Valve Index, which has lower resolution screens than the above mentioned VR headsets, but it still has the best tracking and connectivity. In my opinion, this is still the best PCVR headset. Source: over 1 year ago

If new, I'd probably go with the Valve Index. you'll get the headset, two v2 base stations, and the Index controllers. This kit doesn't require any additional software, beyond SteamVR. You can add some Vive Trackers to the mix and get your full body tracking. Source: over 1 year ago
