It's miles better on Python and most javascript that I've touched (VSCode's ecosystem does tend to have more breadth, and if you're working on something that VSCode has plugins for but Intellij does not, yea - VSCode can be noticeably better for most purposes). Most commonly around stuff that requires better understanding of the structure of the language / project, like refactoring and accurately finding usages.

But yes, for many dynamic languages a fat IDE is less beneficial, especially for small-ish projects (anything where you can really "know" the whole system).
