I use Vim but one thing that VSCode has that Vim does not is the idea of remote containers. With VSCode, it's pretty nice and easy to get perfect auto-complete, definitions, etc. from code running in a container. With Vim, AFAIK there's not anything near as seamless to do the same thing. In fact, I've found nothing that even tries to do it.
