To be honest my Python usage is much less than it was a few years ago. I generally only work in small standalone scripts and some contributions to larger projects every now and again... So I wouldn't be able to help all that much with that. But for your GUI that you want to build, you will have a significantly easier time doing that in Atom than in VS Code. I don't know much about writing plugins for VS Code, but I hear it's much more restrictive compared to Atom in terms of what you can and can't do. I believe that a plugin that can generate a "visual language" is going to be difficult or impossible to do with the tools provided by VS Code, they mostly have specific APIs for dealing with editor windows as text. With atom you could roll your own display stuff but you have the whole power of the browser to do any styling/layout/display you want. You'd basically just need to "render" your UI to a web page, then embed that as a pane in the editor. With some of the others like Sublime and VIM I know even less about their plugin abilities, but I have a feeling it's going to be difficult to do in either of them.
