Vim is great for quick edits and is unmatched in editing speed , especially over SSH.
VS Code is more IDE-ish and has excellent integration with language protocol servers and other plugin tools. It is slower than Vim but has some functionality that Vim does not.
Using one does not stop you from using the other.
VSCode kind of like Wordpress - the more plugins you install the slower it gets. Leave it be and it’s remarkably fast.
