Rift S is leaps beyond better than PSVR (I own PSVR and Rift). Way better tracking, way better controllers, roomscale (if you have room for it), higher resolution, less blurr and a way bigger library.Is it much better than Gear VR and PSVR? The former was nice, but it looks kinda bad and blurry. The latter was considerably better, especially with the ability to dodge and aim by moving the controllers. I also tried an escape room VR game once, where you moved your hands to interact with the environment without any controller; it was cool but I felt dizzy after a while.
I'm really curious at how different a good VR game and headset can be. All this talk about VR is getting me really excited, haha.
I don't know what Gear VR is so can't say anything about it.
