Sublime Text is cross-platform and more modern than Emacs or Vim, and so will appeal to the majority of users who are more accustomed to IDEs such as Visual Studio or Eclipse. Although it is not a free editor, it has a lot of plugins available through its Package Manager (available at https://packagecontrol.io/), which make it suitable for development in any programming language. It is also highly customizable with lots of themes (available at http://colorsublime.com/) and other goodies.
