But above that layer there are pretty big distinctions. Meta is fully on the record that they are all in on making Quest completely use OpenXR as the primary API to the point of deprecating the old Oculus proprietary APIs. They also actively pushing forward the latest WebXR spec into the browser on the Quest, and sideloading of apps in general is straightforward (although you do need a developer account to do it which is unfortunate).
Apple doesn't seem interested at all in open standards at the OS layer, so if you need to be happy with the fully walled garden and proprietary APIs to buy into that ecosystem. It's unclear if VisionPro will support WebXR in the browser it ships.
So in terms of freedom, you will get a lot more from Quest, but its definitely sad that this whole area of computing could end up being the first that has literally no true open platform available.
I guess this means "sideloading" is a privilege they can revoke at their whim, is that right? I hope I'm over-interpreting this (and not blaming you as the messenger).
I just said above they aren't truly open ... so I'm not sure why you're premising your statement on me believing the opposite?
But in terms of how they are are "more" open, you can side load any app you want, and the headset supports open standards at both the app level (OpenXR) and browser level (WebXR).
