I'm surprised they're not porting the windows full fledged version over to Mac. I've used the VS for Mac edition and it's lacking too many useful features that come with vscode out of the box (ex. emmet)
These days, I spend most of my time in VS Code, I frankly don't know if it's less overhead than VS, but it's definitely more responsive. I can't stand working on web projects in VS proper. The plugin model for Code just seems to work so much better in practice. Definitely learned from the past, even if it's a web app, it still works really well compared to alternatives. Integrated terminal and unobtrusive directory tree are godsends.
