One big benefit from my perspective is that due to being terminal based, vim makes it much easier to edit remotely and makes it relatively easy to bring your environment around.
While vscode's ssh option is cool, it still requires that you have it installed on your local machine and while the web based version doesn't have that issue, it's missing other features (like ssh).
So for me the biggest motivator for switching to nvim has been the ability to connect to my machine and work on code from any device (ie even android) anywhere, only needing access to a terminal, and if I need to work on someone else's machine, having my environment there is as simple as cloning a git repo with my .vimrc
