• about Vim :

Vim is a well-known, powerful, highly customizable text editor similar to VI, which improves and adds many features on the basis of VI. Vim is purely free software.

Vim is generally respected as the best of the Class VI editor, in fact the real rivals come from different variants of Emacs. 1999 Emacs was selected as the winner of the LinuxWorld text editing category and Vim was second. But in February 2000 vim won Slashdot Beanie's best Open source Text Editor award, and Emacs was pushed to the second line, with Vim and Emacs also being a very good text editor.
