I don't contest that VSCode has achieved better out of the box functionality than emacs but it still needs a lot of configuration. My experience is only with C++ extension where intellisense update just goes on indefinitely. Navigation to a function takes ages. Then I exclude some source directories and restart VSCode. And not to talk of resource hog that it is. When it works it is pretty good and that's why I stick to it. May be other language extensions are better. I would say it is the best editor with the resource usage of a full blown IDE.
