I think Xreal will likely be your best option right now, but there software support is not so good. Youll likely go down the rabbit hole and learn about viture and rokid and make more informed decision.
I've got the Viture glasses. There's no support for Linux aside from working as a basic HDMI display over USB-C (so no head tracking, the screen stays welded to the same spot). The Spacewalker app on Android is basically a web / media browser, zero productivity. You can't use it like a launcher and launch other apps. There's Taskbar and Second Screen but these don't work on my Sony Xperia (you don't get window controls like resize, move or close). There is a paid app for Linux that uses the Viture SDK. It's supposed to be decent but I couldn't get it working during the free trial (I'm using OpenSuse Tumbleweed). TBH I got totally fed up with the glasses and lost interest in trying anything further.
So this announcement is actually interesting to me.
