Jetbrains products used to be superior. Better refactoring and speed than Eclipse or Atom. However the sale might be a consequence of the fact that free and nearly equally powerful alternatives such as VSCode are competing directly with Jetbrains products to become the developer's preferred editor.
With the rise of Microsoft's free Language Server [1] I'm wondering how long it takes until open source IDEs will be on par with Jetbrains.
