All of them are basically iterations on current customer devices, with main advantages coming mostly from: 1. Apple willing to attach mind boggling price tag to it. You can engineer much more things if price tag is 10x of industry leader (oculus 2). 2. Apple is taking a big shortcuts with external battery, that gives you a lot of extra power, space and thermal leeway.

I’m not saying that they didn’t make something great - it does seem great. And given it’s Apple, they’ll likely have great polish and attention to detail, that make a HUGE difference.

But it’s not a best thing since sliced bread. It’s not a technological breakthrough. It’s “just” a new generation of customer electronic device, that’s better than previous one.
