PSVR2 has:
A lot of bad / noticeable mura in grays. Like terrible at times. And there's not a damn thing you can do here.
Very, very poor edge to edge clarity with text/details due to the fresnel lens. Stuff like using your PC in a virtual screen sucks, same for watching movies, as the clarity just goes down the shitter.
Bad image retention, makes games with high motion even like Synth Riders look less detailed than on the Quest 3.
A very small sweet spot that will often need re-adjusting in higher motion games.
Poor/non-existent MR.
No built in speakers.
No Wi-Fi / Native game support.
None of the side-loaded games from Team Beef, which may change, but there's a good number of great games there.
None of the meta exclusives.
Almost none of the PSVR1 exclusives people want either.
Despite being wired, the controllers will need constant recharging of their batteries, expect ~4-5 hours (like 2 sessions, sometimes not even) battery life.
That said it has its advantages too. Just don't go in thinking it's anywhere close to being the best there is. You're totally overselling it. Quest 3 looks like literally a generation ahead of the PSVR2 in clarity. And it does absolutely run at 120hz. And the FOV is identical too.
