I’d like actual examples instead of “I work faster”, something like “I can move straight to the middle of the file with 7mv” or “I can keep 4 different text snippets in memory and paste each with a number+pt, like 2pt”, things that you actually use somewhat frequently instead of what you can do, but probably only did once.
I work on many different systems, some ancient and some embedded, some both. Vim and friends are ubiquitous. It’s a tool I’ve learned to use effectively by necessity, because other editors weren’t always available.
As an example, many routers don’t offer a graphical environment. There is no option to use something like Visual Studio or notepad++ without shuffling files around.
