I use Atom because it's been around long enough to have plugins for everything. It is very unlikely that there isn’t a plugin for your favorite language. It’s super easy to install plugins and packages (or to write your own!). The editor defaults are great: it’s the best default setup I’ve ever seen for a text editor. One can download this thing and get working immediately.
At the end of the day, most modern text editors are great. I do love Visual Studio Code as well! I often find myself switching between the two for no other reason other than just because.
