Hmm. So whats peoples impressions? I'm a PSVR owner, but considering getting this to access the PCVR exclusives. I don't think I can justify that Valve Index cost . . .
I was in the same boat as you before - PSVR owner and usually borrowing a PCVR set for anything from work. Couldn't justify the price of the Index for purely entertainment, but the Odyssey+ sale really helped tip me over.
Compared to my work's Rift sets, the tracking is worse in the sense that the controllers can get lost when it's not in view of the headset. Secondly, the controller rings are big, so any games with precise movements bringing the controllers together can be compromised (H3VR did this to me for physical reloading actions).
That said, I'm used to PSVR tracking, so it's better than those when it comes to the actual controllers in view, like when the Moves are in front of the PS4 camera. Once you move the controllers behind your back though... lost line of sight.
The majority of what I've played usually keeps your hands in front of you though so I didn't consider it that bad, and for what I paid I'm okay with it for now. The high fidelity of the Index sounds tempting but it felt like a luxury I couldn't go for at the moment, when all I really wanted was PCVR access. If you even consider anything outside of gaming for VR, I don't even think that level of interaction is needed.
My work is design-related so rudimentary PCVR was enough for me, which is still more helpful than only relying on traditional flat screens.
