The comparisons I've seen make it look like the the extra resolution of the Quest 2 over an Index isn't really noticeable over Link. There's less SDE, but it looks less sharp. [spoiler]Hate to give props to Facebook, but it's super impressive for the price.[/spoiler]
If all you're worried about is resolution/clarity, just get a G2. Index fov and refresh rate is higher, and Index controllers/Vive trackers work natively with it if any of that matters to you.
