I'd have to say Allaire's HomeSite 4.5 is what I perfer. I've used Frontpage and Dreamweaver quite a bit but I really do prefer HomeSite. The interface is user friendly, you can save preset bits of html/code, open multiple documents quickly, preview your work.

I use it for all of my PHP and AFP work, and the cost is nice too for such a great program, it is only $99. Which compared to things like dreamweaver is a GREAT deal.
