Started with a Rift way back and recently got a Quest 3. As you’re already aware, it comes down to the games you want to play. I’ve invested a bit in a setup for flight simming, because I love helicopters. Because helis are so sensitive, VR actually gives you much better control (it also increases your immersion, obviously). I replayed Half Life Alyx recently, and it’s still great. And then I spend a bit of time in Beat Sabre several days a week. Oh, and there’s a puzzle game where you just use your hands to match a set of blocks to a 3d shape. It’s great not always using controllers. In terms of the quality of VR - it might not have improved enough to ‘cure’ your nausea yet. The quest 3 was a big step up in clarity compared to the Rift, but your peripheral vision is cut off, and it’s still a ways off from normal vision.
