I purchased a Reverb G2.
The resolution is not as good in the Pimax, it is a generation older. I honestly love the FOV but its a trade with res. I know I miss the peripheral abilities of the Pimax when using the Reverb and to be honest, I'm not that impressed with the sweet spot of the G2. I don't consider the Reverb a step up in overall immersion, more a lateral move.
