Hi,
I have used both and I think it depends on how much you want to do with the program. Frontpage is easier to learn but it does add that irritating code on its own. Although the latest version may have a way to turn that off in the Options menu.
Dreamweaver is the better choice if you will be doing a lot with graphics, Flash or web applications (PHP, ASP and Marcomedia's ColdFusion). It is easier to work with all those at the same time with Dreamweaver. As shiara said, Macromedia is the industry standard. As far as how easy it is to use, Dreamweaver has two ways to work on a webpage. You can use the Design View which is as easy, if not easier, as Frontpage and much like using a word processor program. When you are ready to advance you can begin hand coding your HTML in Dreamweaver.
I have just started a series on Macromedia Studio MX and I will be writing tutorials for all of the software in the package including Dreamweaver. Of course, you don't have to purchase the Studio version. You can purchase Dreamweaver as a stand alone program.
