I think the Quest Pro feels clunkier and is harder to adjust than the HoloLens. I have a big head, and I’ve struggled to adjust the front dial while the device is on my head.

The Hololens also has a top head strap that makes the weight more evenly distributed for longer use which the Quest Pro does not.

I’m not a huge fan of the Quest Pro to be honest

The HoloLens is actually very comfortable. I regularly wear it for 2-3 hours at a time. Battery life is usually the limiter there, not comfort. It’s not like wearing a VR headset, where there is a lot of pressure on your face and the screens cause a lot of eye fatigue. The Hololens is also a visor on a swivel so you can “get out of mixed reality” very quickly.

I don’t use Magic Leap, mostly because it requires a puck with a cable and a controller which don’t work for the use cases at my job. But it is used for surgery in China, and surgeons would never wear it if it wasn’t comfortable for multiple hours. Magic Leap 2 also has the best field of view of any mixed reality headset
