If level of customizability is your main metric:
Emacs can go from this: https://emacshints.files.wordpress.com/2013/09/spash1.png

VSCode killed Atom long before GitHub acquisition.
Well, if you just want a custom VSCode theme, you can try Theme Studio for VSCode: https://themes.vscode.one/. Login/signup required, though. No affiliation.

You can override any color you want in VS Code with a couple easy settings in your settings.json file: workbench.colorCustomizations and editor.tokenColorCustomizations

You have to package it if you want to make it easy for other people to install, but if you just want to play with it, just open settings.json and start feeding it colors.
I've made extensive use of this and it is a killer feature of VS code for me. Still, I wish it supported all of CSS like Atom did.
You can do a lot of customization in VSCode. Not as much as Atom, but way more than the average editor. I'm not positive whether or not it would be enough to serve your case
there is an extension that lets you set arbitrary css in VSCode, albeit it's a bit cumbersome to use.

But it's still really sad to see. I use it because it was trivial to CSS style it to match my Desktop. It's comfortable to me in a way that other editors thus far have not been.
Are there other editors with this level of customizability? I know VSCode and Sublime support theming but from what I can tell it involves installing pre-packaged themes.
