For games, I feel that the Q2 is still the best because most games haven’t upgrade their visuals yet and because the original controller has the best tracking. Also it’s about half the price of Q3. It won’t last for long and the frenel lens aren’t great compared to the new fish eye lenses.
Quest Pro has the best form factor. I like the open headset style. Since it has eye tracking, it also has the best performance for PCVR streaming especially for Steam since Steam link supports eye tracking
Quest 3 has the best performance and resolution. Resolution is now good enough for doing work in VR. Some games optimized for it also look close to PCVR visual fidelity. Wireless PCVR streaming is terrible though, and I’m not sure why.
