Personally I see vi as "the panic editor", in the same way you'd think of a panic snack. It's not glamorous, but I'd reluctantly take it over nothing if my system was toast and I needed something to pry it back to life. I like helix and use it when I think to but I very often unconsciously default to nano because it's just the easiest text editor I've seen in a terminal. It's the path of least resistance to use for That One Basic Edit I Need To Make.
