Before switching to Visual Studio Code, I used Atom. In contrast to Atom, Visual Studio Code is faster, provides more built-in features, and fails less often.
I started using Visual Studio Code because Atom was oftentimes extremely slow on even basic tasks, and there were bugs that could freeze the entire window if you dragged something the wrong way. Atom also didn't have as many integrated features as Visual Studio Code, so I had to find all of the best extensions. Even with the right tools available, many language extensions were frequently buggy, ineffective, and slow.
