I always stayed clear of frontpage after all these horror stories about it. I've used dreamweaver abit but I prefer notepad over them both. A good editor is actually coffee cup editor 9.1 or something I think (not sure on latest version!) But to answer your question, dreamweaver is miles better.
to be honest you cant really compare them together imho
they both target different audiences imho. frontpage is more userfreindly. its more one click orentated. with dwmx it gives you more advanced options to what you trying to do in a more prof. way.
i just prefer to use php designer 2005. works loveley for php, js, and html etc
