I'm trying VSCode now, but I still switch back to Sublime for SublimeGit. It's such an integral part of my workflow, and VSCode's built-in git is no substitute.
- You can easily see the status of each file (new, modified, or staged).
- You can easily stage all files, each file, or just specific hunks of specific files.
- You can stash and pop stashes.
- You can amend a commit.
- You can do all of that from the keyboard, without touching the mouse.
I imagine you can do many of those things with VSCode, but it's so effortless in Sublime. I haven't learned the same workflow in VSC yet, and since I do all of those things frequently, I'm really attached to SublimeGit.
In the same way, I use VS Code mostly now (for node stuff) but I still load up Emacs and use Magit whenever I need to do serious version control, meaning basically anything more than just "glance at the changes and commit everything."
