First, I'll say that N is absolutely my go to choice if I ever get my hands on it.
With that being said, hanging is somewhat appealing to me because if you get all the placements and positions right, you pass out very quickly and with little to no discomfort. To elaborate a bit more on the placements and positions thing, if the rope doesn't restrict the major veins pulling blood out of your brain AND the rope doesn't compress your airway, it actually feels like nothing more than a tight tug -- no head pressure buildup or choking feeling.
I've practice hanging a few times (using a somewhat abrasive, taut rope), and it wasn't too bad. It did, however, take me many many tries for me to figure out where the sweet spot for me was, and even when I did that, I had a hard time replicating this. Doing this was extremely taxing as well, both physically and mentally, so even though I was only practicing, I could imagine getting super frustrated with it if I was in the mindset of actually wanting to go through with it.
The few times that I did find the sweet spot though, the lights would start going out in just a couple seconds, and I'm pretty sure I would have passed out if I gave myself a few seconds more. The reason why it didn't/wouldn't kill me is because again, I was only practicing (partial approach too), and purposefully gave a lot of rope length so that if I completely lost consciousness, I would fall to the ground and eventually wake up. This made compression a bit awkward, but it still wasn't too bad.
