I had the MQP for just under 2 months and returned to Best Buy. It was definitely a step up in quality over the Quest 2, but not worth the price for my personal usage (almost only porn). I will say though that the passthrough was pretty promising - I'm sold on passthrough as a concept although it has a long way to go.
Meta Quest 3, though not confirmed in title, is confirmed in concept for release this year by Zuckerberg, and it will carry over MQP's passthrough and likely have higher resolution (MQP resolution kinda sucks for the price, although the lenses do improve the overall experience).
My main point: Once the Quest 3 releases, we're going to have 10x more people with an incentive to try/use color passthrough.
