I bought a Quest 3, mainly to play around with VR/AR development, and so far in using it, it has me more hyped for the Vision Pro.
The hardware on the Quest 3 is fine, especially for the $500 price point. The passthrough works well enough that I can work in VR, doing iOS development (The main issue I had with past headsets was passthrough not being able to see/read phone displays, without taking off the headset.) Virtual displays in the Quest 3 look about like using a pre-retina monitor (Think 1080P monitor at 27".) Software is the place where Apple will take the cake. Hand tracking has improved a ton on the meta side, but gestures are still finicky, and "tapping" on virtual displays always takes multiple attempts before it takes your input (Even though it shows your hand going through the button, it just doesn't actuate.)
The thing is - the Vision Pro has multiple things going for it - way higher resolution displays, way better quality color cameras, likely better lenses, and likely a way better image processing pipeline with a dedicated reality processor. Also the biggest thing - software. Meta's offering is surprisingly polished in terms of things like ease of setup and just putting the headset on, but it is still just generally buggy - you still get a lot of hitches where the image will freeze momentarily, apps will open to black screens, and other just jarring transitions. I'm sure a lot of things will eventually be worked out (And they work this way because passthrough on the quest 2 was garbage) but it has a long ways to go.
The one thing Apple has done correctly is defaulting to MR. When you put the headset on, it shouldn't be a blank screen and drop you into a virtual environment (Q2/Q Pro did this.) Meta has finally figured this out, and they now default to MR on the Quest 3, and you have to manually flip to full VR. But it is still a VR first headset, and you feel that with the jarring transitions into apps.
Basically - Meta Quest 3 is the Android, to the eventual Vision Pro "iPhone". Yes, it is 7x more expensive, but I think it will really be in a completely different class in terms of experience.
