This is going to be one of those things where everyone shouts and stuff so I'm just pre-emptively putting it out there that this is only my experience and I can only speak for myself.
But in my entire life, now in my 40s, I have met exactly one person who used emacs enough that I knew/they told me. I don't really have a dog in the fight between vi and emacs. Back when editing your xf86.cfg was something you had to do fairly regularly to get your gui back after looking at it the wrong way or saying something that offended it I would use vi just because the barrier to 'typing some words and saving the file' is lower, but I have no great appreciation for it either. I feel like both are... suitable for the limited environment they had, useful in a pinch, but everyone much prefers using something more intuitive.
