I guess much depends on what features you want and what you are used to earlier.

I guess that Notepad is the editor I most often are using when editing or building web pages/sites.

But I can recomend two other nice editors aswell, one simple editor and one wysiwyg editor, both are well worth checking out.

Macromedia HomeSite 5.0
Macromedia Dreamweaver

Hope you finds what u are looking for.
