The pure text editing is just a tiny detail. I exclusively use vim keybindings inside Emacs, as many others do.

Emacs makes extending the editor a breeze. As a new user this just means that you have packages (like VS 'extensions' or IntelliJ 'plugins') for, well, everything. For a more advanced user it means you can automate away many things that are a pain in the ass to repeatedly do in your daily work.

I'd suggest you try Doom Emacs when you have a couple of free hours to get a taste of what a properly configured Emacs can do. And, once you are on it, just press "SPC f p", select 'init.el' and check what popular packages you can activate just by uncommenting a line and doing a 'doom sync'. Then press "SPC f p" and select 'config.el' to check how even "configuration" in Emacs is just elisp code. You are just running a piece of code you can edit and even debug from itself _while_ you are running it (although that'd require a bit more explanation of how it's done) . This should give you a taste of what Emacs is about.
