Vim is very simple (a composable language for editing, straightforward integration with cli tools, easily extendable,...). Emacs is simple (Major mode that dictates main operations and display, minor modes for additional features, integrations between them can be described more as a complex web than a simple graph...).

VS Code is easy (helpful suggestion for plugins, Familiar IDE-like interface, default setup, ready to hack on projects,...), but scratch that surface and the complexity appears (behemoth web engine, settings all over the place, app store like marketplace, extension are full blown software project,...). All the cons of IDE with none of the pros.
