The thing about an IDE is how tightly integrated all of the tools are.

If you list the features individually, surely there’s a way to add most of them to your text editor of choice - but the downside is that they’re now all fairly independent features, may not work as thoroughly or covertly, and you might end up with a slower editor altogether.

Not to say IDEs are the peak of performance - but they tend to provide more robust tooling than is (easily) available in e.g. VSCode/emacs/neovim/whatever.

It’s like using a specialized power tool - it’s not the right tool for every job, it’s probably a bulkier package, but if you know how to use it an IDE can make your life a lot easier for the right workload.
