Atom is also Great :)

and Microsoft made VSCODE open source on 2016 https://www.youtube.com/watch?v=OnkYnm-WiVo

Both are based on electron, But on atom it took a while to open the editor and while working on big projects, it perform slower day by day, But on VSCODE it open up quicker than atom, also it does not perform slower as i am working on the same project.
