**Bottom line: the Microsoft HoloLens 2 is the better buy for most people, unless you need the lighter fit.**

- Buy the Epson Moverio BT-45C if you want the lighter 445g fit (vs 566g) and you want adjustable lens dimming.
- Buy the Microsoft HoloLens 2 if you want the wider 52° field of view (vs 34°), you want smoother 120Hz motion (vs 60Hz), you need full 6DoF positional tracking, and you want spatial audio.
