ConTeXt editors

Hans Hagen (the author of ConteXt) uses SciTE and, more recently, textadept. He also wrote support files for those editors and these are part of the ConTeXt distribution. The ConTeXt distribution also comes with a full set of support files for TeXWorks. The support for the various other editors mentioned above and on the ConTeXt wiki page are written by other people.

If you want the best possible editor support, you should probably use one of the three that are actively supported by ConTeXt, but I have heard that Emacs and TextMate (at least) are also working well.

As a devoted Emacs user I prefer using AUCTeX, which supports ConTeXt. Another useful Emacs addition is etexshow, which is an Emacs port of texshow, a browser for ConTeXt commands (not all, but most of them).
