VSCode is quite restrictive in how it can be extended actually.

Atom is much better, and feels closer to Emacs in terms of allowing you to extend and modify almost every part of it.

That said, Emacs is just the king. Not only can you really just change absolutely everything, it is really easy to modify it all at run-time on the fly, which even in Atoms isn't quite so.

I had settled on Atom for a while, but the slow performance and high memory use made me switch to Emacs.
