Yes I used emacs at school 15 years ago, and I agree that it was great for development ; with OCaml at the time (and also C with gdb integration, and 68k assembly later on) we shared a few tips with other students and the workflow was convenient for dev.

But vim is ubiquitous which is a huge plus when you are like me always connected remotely on a different machine. Once I learned a few shortcuts I never went back (and never dug into the tool itself actually, I can't even run a macro ; I'm still faster than most people I know with an IDE).

The only thing I was impressed with is I think phpstorm, watching a laravel dev crafting an SQL query. If I ever get serious about developping I would look into this kind of things (not just for SQL but also framework and module functions), especially if I can get vim movers, and a screen that isn't bloated. VSCode displays like 15 things and I'm only interested in 1 of them 99% of the time for example.
