BBEdit has been my goto editor since 1995. I own copies of many other Mac based text editors (Alpha, TexEdit, TextMate, vi, etc), but to my tastes BBEdit has always been the most feature rich, powerful and clean editing environment.

Other editors that I use regularly have some additional strengths in a given domain, such as CSSEdit or MultiMarkdown Composer, yet nearly everything I do starts in, passes through or ends in BBEdit.
