I love Nusphere's PHPEd, and would not be without it in my toolkit. However, I still find my editor of choice to be Boxer, a program I have been using for the last 18 years.

This is not a case of not wanting to break old habits, or a resistance to change. Over the years, I have tried most of the fairly decent editors on the market. With literally every other editor I have tried, in the course of work, I end up pulling up Boxer for one utility or another that is not provided in the editor I am using at the moment.

Boxer is feature rich and a superb tool for any programmer.
