If you use vim every day, the common operations become muscle memory, I don't even think about jumping through the file, find and replace, block edits etc, they just happen.

For me personally, the context in which I edit files changes constantly - sometimes it's inside a Docker container, sometimes it's on a server, sometimes it's on my personal Linux machine, sometimes on my work Mac... Vim is easily available on all of those, and I just use the default configuration.

I do see my colleagues benefit from VSCode. If my work environment was very consistent (same computer, same language) I think you're right that I would possibly gain in productivity from using VSCode (with Github Copilot, perhaps). But my work environment is not consistent, so Vim it is.
