It's funny, when I put on my Pimax 5K+, I was quite disappointed. I thought to myself, "this is what all the fuss was about?" Granted the higher FOV is better, but isn't exactly Earth shattering. I think it also had to do with the 5K+ isn't as nearly sharp/clear as I was hoping for. And there are a ton of god-rays.
It really doesn't look any better than a Vive Pro etc. I think the Reverb with that high of resolution with RGB stripe is going to blow other headsets out of the water. Especially since you get can Vive controllers working with WMR now.
