An editor is a tool, and like many other tools, what fits me may not fit you.

I personally use emacs, but I have also used it for over 20 years, and so my configuration is well worn, fits well into my hands, and responds the way I expect it to. I am able to use vi/vim to do many things, but it does not have that same comfortable feel that emacs does.

I would recommend that you try out some tools and find out what works for you. There are some good suggestions (other than perhaps notepad :-b ) in this thread. Look at their documentation. See if they are easily configurable. See if they provide utilities to make some of the tedious work automatic. Search and replace? With regular expressions? Macros? Whitespace configuration? Compile while typing? Spell checking? Boilerplate code? Running test suites? Refactoring utilities? Can you add an extension yourself? Unicode? There are many tools that an editor can offer. How they hook into the system can be comfortable for one and unacceptable for another.

Some tools are also complex, and in the hands of an inexperienced craftsman may feel clunky and over-featured. Once experience is gained, a feature that may have felt extraneous becomes well used. Learning an editor (or a set of editors) is an investment that may take some time, but will pay off in the long run.
