I own one of each, and develop for the Vision Pro through my job, it's the very same story it's always been. Apple hasn't 'invented' much here, but the magic is in how it's assembled, even in its current state, using apps in a 3d space feels better than anything the quest has ever done. Even simple things like 'touching' a panel just feels more natural on the vision pro than the same experience on the quest, mostly because the quest does things like forcing the ghost hand to stop at the surface of the window, instead of continuing to track your hand through it and just using the intersection as the touch point. It's a small difference in the interaction that makes a world of difference in usability, which Apple is very good at.
