I'm guessing a lot of cruft built up on atom as it was iteratively built on top of developing front-end frameworks and transpilers over the years, compared to vscode which came on the scene much later when a lot of this had already settled. My guess it's just an older project with many times more contributions that accumulated legacy cruft that takes time to fully expunge. I'm also not convinced the feature set is identical. Atom comes with a lot of language support, customization options, and extensibility out of the box.
