**Bottom line: the Rokid AR Spatial is the better buy for most people, unless you need a built-in camera.**

- Buy the Epson Moverio BT-45C if you want a built-in camera and you want adjustable lens dimming.
- Buy the Rokid AR Spatial if you want the wider 50° field of view (vs 34°), you want the lighter 75g fit (vs 445g), and you want smoother 90Hz motion (vs 60Hz).
