Let's say you look at `git diff` and notice something needs to be changed. What do you do now? You need to quit, open the file, find the line, do the change, save and quit. Now you need to reopen git diff and scroll to the old position. This all takes a lot more than 5 seconds on the terminal.
Another scenario: You type `git status` and see a file called `src/a/very/long/path/file.c` hasn't been staged yet. Now you need to type that file path for git add or git diff. Takes more than 5 seconds, but it's just a simple click on a + symbol in VS Code.
The only 'plugins' I use are a keyboard shortcut (cmd+space) which puts me in a terminal window and rupa/z[1] for jumping into a project directory.
