I'm going to be honest and say that the Quest 2 is better than the Index if you can get over the Facebook shit.
>Expensive but with quality control issues (expect having to RMA your controller and potentially your headset)
>Setup is a pain in the ass
>Small sweetspot
>Requires a decent PC in order to run a lot of games because a bunch of them are unoptimized messes and even then some of them just run like trash

I still like using my Index because i'm a big dumbass with a lot of disposable income looking for the most immersive experiences but with how fucked the PC market is right now a standalone headset is the way to go. I wish Valve would use some of their multi-billion dollars to actually create a standalone headset with a Steam storefront but Valve is allergic to actually doing anything other than passively generating income from their games or the store. Instead focusing on gimmicks that honestly don't work out when you don't have a strong install base.
