I own a mac and have found a lot of success with Smultron.

Additionally I have heard great things about Coda, but it comes with a steep price tag.

TextMate for Mac, hands down. However, I have wondered if bbEdit would better serve my purposes.

I like TextMate for my regular editing, and SubEthaEdit if I need to collaborate on some code. Both only for Mac.

Coda is really funny!

Gvim, and Firebug mostly...once somethings relatively built, and I view it in firefox w/firebug, I make my changes there, and then once I'm happy with the results, I copy my changes into my tpl or css file.

I use dreamweaver usually for the basic wysiwyg stuff, like if I need to reformat a bunch of paragraphs, or some kind of table (NOT for layout), lists etc with no styling at all, then it comes in pretty handy...

gvim

Panic Coda + CSSEdit!

Bluefish, nice syntax highlight and is fast; sometimes i use Gedit for minor changes

I use Smultron for Mac (a free text editor) which is great for XHTML/CSS/Javascript/PHP

But Im a mac user so I use Dreamweaver to update files for my wordpress site as I can just edit and use it's built in FTP in a few clicks.

For windows I used to use HTML KIT which is really handy.

Also Top Style Lite for windows is good for CSS files

I've recently picked up Coda, too, and I'm really liking it... but I'm still in the trial phase and, yeah, it's pretty expensive. Otherwise Smultron on my Mac, because you can't beat the price tag.

On Windows it's UltraEdit all the way.

TextMate and WordPress Bundles

When I developed code on Windows boxes in college I loved UltraEdit. What a great piece of software.

Editpad Lite.

Long time I used Dreamweaver and Programmer's Notepad. But I don't like Dreamweaver very much.

I use Expression Web since it supports PHP (Beta 2 works really well!).

TextMate for the win.
