So far the only good one I have seen which trumps Rift and Vive etc on clearness is the Pimax 5k+ and 8k.
To me the best VR test for clarity and resolution etc is Elite dangerous, as the common problem right now is reading text while sat in the cockpit. Even the Vive Pro didnt help that much.
Pimax 5k+ was almost crystal clear, but the headset itself looks terrible and not very comfortable. Lets hope this one will be the new king of the hill. Certainly looks decent.
