Yet if you made that argument people would look at you funny, and rightly so because when you're comparing Lamborghini's to other cars you usually talk about things like car performance, air drag, etc.
Likewise, on a technical level the Vision Pro is superior in pretty much every way except the FOV is slightly smaller and it has an external battery pack. The last of which is debatable because being external makes it swappable and upgradeable.
Otherwise, the vision pro is an incredible piece of tech. Better lens technology, better eye tracking and foveated rendering, better passthrough, superior display quality, far higher pixel density, superior hand tracking, real-time environment mapping with LIDAR, higher quality build materials, etc.
All of those things add up and push the boundaries of AR/VR tech. Is it pricy? Obviously, but I wouldn't be surprised if the build cost is significantly higher.
