I moved from WebStorm to VS Code and haven't looked back. Code is generally faster than any IDE I've used (at least for JS work). My understanding is the Go support is very good. No idea on Python. There should be extensions for both that should be easy to install.

Code has become hands down my favorite editor. I don't use the debug often, but it's passable. Just depends on your needs and use. I'd suggest giving it a try for a couple weeks (just to get past any initial pain points).
