The big appeal of magit, at least for me, is that I can quickly do it with the keyboard. Open magit, press “s” on each hunk to stage it and magit moves to the next hunk, then “c c” to write a commit message, C-c C-c to commit, then “q” and I’m right back in the code. If you need to edit a hunk you press enter on it and it drops you into the file.
This is much much faster than doing it with the mouse, and keeps me more in “the flow”. In general Emacs becomes powerful because it’s full of little tricks that add up to much tighter feedback loops which is so helpful when coding, to keep your attention on the problem you’re trying to solve. And it is trivial to add your own “little tricks” to tighten the feedback loop for whatever you’re doing.
I get that. For me VSCode is pretty clunky in terms of replacing what I like about Emacs. Writing a plugin is way more of an exercise than writing a couple lines of elisp to change something or add some new functionality, things are not self-documenting, it's not nearly as easy to open a REPL and start poking around programmatically at open files, etc. These are the things that I value with Emacs and that make me more productive.
