I mean, a lot of it is just the kind of complex one-off text transformations that would normally require a throwaway script or program to express. (They do in Emacs too, but you can write it as inline Lisp forms in the replacement side of a PCRE find-and-replace, and not deal with any boilerplate.) Refactors and stuff like that all happen through LSP providers, just like in VS Code.

If you're looking for a strong reason to think Emacs is worthwhile as a totally new user, I'd point instead to Magit, an extremely powerful and comfortable git porcelain, and Org-mode, which is simply the most powerful and flexible single-user notetaking/outlining/live code notebook tool yet created. Those are the two Emacs features I see most often mentioned as the subject of sentences like "I don't use Emacs for anything else, but I do use it for X because nothing else comes close".

That said, as I mentioned above, I'm not really here to evangelize Emacs. It definitely does have a steep learning curve, enough so that unless you see a clear killer feature (in my case, TRAMP's transparent remote file editing, since I edited remote files a lot in those days), it's not likely to be worth the trouble.

This. After having fiddled around with Emacs over the weekend, having tried out Spacemacs and Doom and working through some tutorials, I concluded that I definitely won't replace VSCode with Emacs for coding any time soon. As a Git & PIM-Tool, it seems to be useful though.
