I can imagine it's cool of they presumably have a really wide AFoV as well - real starwalk kind of stuff.
However, they say it adds a further 1.2 magnitudes to the naked eye, whereas a 50mm pair of binos would add 4.4 magnitudes which I think might be more useful than the incredibly large field of view.
Look, I'd love to try them - 36 degrees TFoV sounds amazing! Heck, maybe I'll even get some one day, but I'm looking for something to help me see enough of a constellation to star-hop to targets.

I thinks it’s something you just have to try for yourself. The Galilean optics mean the exit pupil behaviour is different and of no concern. There have been some discussions on CN and post #3 in this thread answers it well.

I first bought the SvBony 2.1x42 when on sale and was pleasantly surprised just how many extra stars I saw over a large field. I then bought the Orion 2x54 and these take this type of viewing up a notch with their massive 36 degree true field of view.
Basically you see more stars at very low power. The Pleiades is wonderful in its full context in the sky amongst Taurus with so many extra stars showing yet still looking like an unaided view. The 2x54 are a nice complement to the Orion 9x63 mini giant which are great for getting in closer giving nice bright images but only 5 deg. true field.
Your other option is some retro 7x35 which used to give 10 or 11 deg. but we’re short on eye relief. Not sure if there’s anything more modern giving the same. Out of all of them I would only call the Orion 2x54 true constellation binoculars. Taking Orion and all of Canis Major in one field gives another wonderful view.
