This is where people just don't know. Oculus hardware is already 2-3 years behind on release, they've got 5+ years of R&D to catch up by that metric. The Valve Index was released in 2019 and it's still the best hardware in the game, with rumors of new hardware on the horizon with recent hires.

Inside-Out tracking as on the Quest is great for portability, but unless you are massive enough to curve light around you, tracking fidelity will always be sub-par in comparison.

Not being tethered is nice, but the system is a glorified cell phone mainboard and screen in a case for your face, the necessary battery and performance limitations will be there.
