Count me in as a Rift S owner after the HP reverb...
I was one of the lucky HP Reverb owners. It was a fantastic headset and soooo close to being perfect. Sadly, I was getting the shutdown and flashing issues with it. HP on their part were fantastic. Replacements are not being given, but refunds are.
I couldn't do without VR so grabbed a Rift S last week off of Amazon. To be honest, I'm pretty blown away by it. The resolution is not Reverb level, but quite honestly, the reverb's 250 dollar premium is not worth it *for me*. Performance wise, the Rift S is better (I5 8700K, RTX 2070) which would make sense.
In short, I'll stick with the Rift until the next gens come out. It's been a surprise.
