It's useful to have a more full-featured editor when having to work from the command line. If you don't work from the command line often (I do), or you're already comfortable with another tool, then it may not be worth it. If you do / want to, it's a good tool to have in the box. I never got the hang of emacs, but either one should serve someone in that boat well.
Addendum: I use the vim extension in vscode on a Mac and I love it because I barely have to touch a mouse. It is by no means mandatory in IDE-land though.
