UltraEdit is to Windows what BBEdit is to MacOS.

I know, that doesn't add much to the conversation. :)

Indeed, as a long-time Emacs user (and vi before that), it was hard to read past "world's best text editor."

As a Vim die-hard who had ultra-edit as default text editor in my Windows box at work before I installed vim, I can only reply "nothing". It is significantly far from being the best text editor in the world.

Its main selling point is that it's better than Notepad.
