- Same interface for analysis, scripting, and building more complex multi-file pipelines. I can also use the #%% notation to break up and debug scripts, which is probably teaching me all sorts of bad habits but it's something I find helpful.

- Similarly, as another commenter in this thread notes, .ipynbs just don't play as nicely with the other dev tools (e.g., Git, Black) and generally feel like second-class citizens in VSCode.

- I much prefer having the VSCode interactive window on the right, as opposed to having my output dumped out below my code block. I now find using the classic notebook style makes the document much longer and harder to navigate, particularly as I work with text a lot and I'm often outputting large chunks of text for inspection.

This noted, I think this is all possible because I'm rarely producing my final products in notebook format. Neither my boss nor the stakeholders I typically present to can (or have any inclination to) read code, so I don't really need a format others can execute or inspect. I just take the charts and figures and dump to presentations and other normie-friendly documents.
