I personally like EditPlus. It's like $20 - $25 dollars, but the amount you can do is great. I've tried others, and EditPlus just gets down to what you need: A great editor, without the bloat.
Dreamweaver I've found adds useless code to my useless code, which confuses me. I've just found it to be a good reference for making quick and easy stuff, the tweaking or recoding it in EditPlus.
UltraEdit, I didn't find very user-friendly in my eyes. It was a great program, but I just didn't like it.
Notepad2, didn't use it much, but from what I can tell, is a defininte step up from WordPad and Notepad.
