Seriously? Mac OS X has the best of both worlds: vim and emacs come pre-installed and we have the best of the GUI editors like BBEdit, TextMate, Espresso, SubEthaEdit, Fraise, Vico, etc.

As for BBedit, it's pretty much a HTML editor with syntax highlighting for some other things.

BBEdit kicks ass. Yes, it has great HTML tools(http://www.barebones.com/products/bbedit/benefitsstandards.h...) which were updated and enhanced recently in version 10 (http://www.macworld.com/article/161180/2011/07/bbedit_10.htm...). But it can also handle the hairiest tasks you can throw at it. Being a hardcore text editor is great and all; where it has always shined is supporting Mac OS X technologies: AppleScript(http://macosxautomation.com/lion/applescript.html) (scriptable, recordable, and attachable), Automator(http://www.barebones.com/products/bbedit/automator.html) without sacrificing the Unix goodies--it's scriptable using Perl, Ruby, Python, etc. I don't know of another editor that has a document type (Unix worksheets http://www.barebones.com/products/bbedit/benefitsintegrate.h...) just for executing shell commands without leaving the editor itself.

I would put BBEdit's feature set against any editor on any platform.

I have no affiliation with BareBones; just a satisfied customer for many years.
