vim might be arcane compared to Notepad, but I've been successfully using vim as an editor of choice in ssh pretty much throughout the whole uni without knowing more than :w and :q (at which point it basically was a notepad). I was ever completely lost in Emacs though, with its nested C-x, M-x seemingly without rhyme or reason. I wouldn't "outright" reject that hypothesis without more scrutiny.
Anecdotally, I've been an Emacs (Spacemacs) user for a few years after that, and I never got used to all the commands I would use on a daily - but not hourly - basis, having to always look those up. But, as one of the other top-level posts said, what made me switch in the end were the language servers.
