I bought the "Launch Bundle", since I didn't have the Move controllers or a camera. I actually preordered 2 of them, one for my wife's PS4.
But since my wife got motion sickness on my Oculus Rift, I let my buddy pick up the second one, since he didn't preorder any and liked using my Rift.
He said that he didn't determine a massive difference in resolution between the Rift and the PSVR, and was blown away by some of the demos that came with the disc--while others, like DriveClub, looked like they were so low-res that he hated them.
I still haven't opened my PSVR, as the main reason I picked it up was for Ace Combat, and things I couldn't do on the Rift.
But it's got a pretty bundle box!
I still think that any VR title that puts you in a seated position, some sort of "cockpit" game---planes, cars, tanks, mechs, you name it---will be where it is most impressive. I loved ADR1FT on the Rift, but you're still inside of a space suit. I've used the VR Desktop to play everything from World of Warcraft to The Witcher to Gears of War 4 in VR on the Rift, and it's just....weird. Either it's a floating flat image that is really hard to explain (like sitting in the front row of a movie theater, best way to put it), or you curve the screen and it wraps all around you where you're so zoomed in it's sort of claustrophobic.
But the "sim" games and things where you're in a cockpit or seated have all been unbelievable. I'd look at something like EVE Valkyrie or Elite Dangerous as an example of how immersive stuff like that can be.
