I have used the following editors:
2. HTML Kit
3. Net Beans
4. Coffee Cup HTML Editor
I've never used Vim, the biggest issue with me is having all the best plug-ins installed. The auto-complete is a big issue, likewise with the shortcuts for quick coding. So far I am really loving Notepad++. It's by far the best editor for myself. I use this with FingerText and it's by far the most productive.
I found NetBeans too hungry on memory. HTML-Kit has an issue with UTF-8. Aptana was selective on opening files, occationally it crashed, but had a great interface and took much less memory than NetBeans. So for my I stuck with Notepad++.
I did not mention Dreamweaver :) I should have mention it somewhere. WYSIWTF!
