I had the chance to try only one of those, so I cannot make an informed comparison: one really has to try the device because I think that there is almost no relation between marketing videos and the actual experience.

My interest is mainly the healthcare sector, and while I have in mind a few applications, I think that for now they are not able to offer something a smartphone in the pocket of a doctor with a properly designed app, cannot do in the same amount of time.

If I had to make a wild bet on what will be the first successful consumer application of AR glasses I would say glasses for cyclists: the user can really benefit from not having to watch away from the road and we are already used to see them riding with funny glasses anyway :-). (in fact it seems there are already a bunch of companies focusing on that).

I've used both the Hololens and the Moverio.

Hololens is kinda neat but gesture recognition isn't there yet and the limited FOV really, really sucks. That's the biggest problem with any of these.

The Moverio is setting out to be pretty modest--think "Google Glass screen projected in field of view, but not shit"--but the execution there is solid. It also plays very nicely with glasses.
