How would you design a headset?

It seems headsets now still are designed around either comfort (the MeganeX or Bigscreen Beyond), or for Price (the Quest 3S is a great example at a really low price) or clarity (like the Crystal Super or Varjo XR4). There are no extreme field of view headsets anymore like the StarVR One or the Pimax 8K. It seems fresnel lenses are dead, only the Playstation VR2 used it. But how would you design a VR headset? QLED or MOLED, which lenses? Focus on price, clarity or field of view, or comfort? PCVR or standalone?
