I tried out a HoloLens at a rich friend's house and had a similar experience, despite it also having a small FOV. It blew my mind and instantly registered as a really big deal. But as another commenter here pointed out, the hardware isn't there yet, and when it arrives it will require a vibrant software ecosystem. The difference is that Microsoft seems to understand that.
Counterpoint: I thought it was really, really cool when I tried it for a couple hours. I have no affiliation with Magic Leap. The Magic Leap unit I tried was a friend's (so it wasn't as though Magic Leap sent me a free unit to try out and therefore could have biased me).
I tried it a couple years ago at PAX Unplugged, and that was exactly my reaction. I felt like I was putting a lot of attention into shifting around my direction to frame the AR, and searching for content, because I was looking through a pipe.
