VS code is not an IDE, its more similar to Sublime.

In comparison to Sublime, it is indeed slower and more resource inefficient- however, it is free and good enough.

Not everything boils down to technical purity, there can be other important factors.

That used to be true but with plugins vscode really has eaten the whole IDE workflow for most people

		That’s true of sublime text too. and vim, for that matter. Perhaps a useless comparison if one thing can be converted into something else; it doesn’t mean that the base of a thing is the thing that can be evolved into.
