I use VsCode+Sublime the same way you use PyCharm+Sublime. Vscode feels like a heavier ide to me with all the extension 8 have set up, but Sublime has always been quick, lightweight, and able to handle anything. Whether that's note-taking, skimming a hex dump, looking at arbitrary Csv's I've always been happy.
Although maybe I'm biased ever since Sublime introduced me to the concept of multiple cursors. It's so engrained now that it's the first thing I change on a fresh vscode install
