Actually, I find site management in the two is about equivalent. Where DW
really shines is in the following areas -
1. Extensibility - there is a huge community of 3rd party developers adding
functionality to DW. Not that there are not similar developers with FP, but
the size of the communities is different by an order of magnitude.
2. CSS support - in DW, the CSS support (particularly in the new DW8) is
huge. The whole program/UI is geared towards the full use of CSS on your
pages - FP seems rather awkward in this regard.
3. Server-model capability - DW has broad support for ASP, .Net, PHP, JSP,
and CF server models, and can write application code based on these models
right out of the box
4. A less 'intrusive' user interface - FP's interface can be downright
byzantine at times, trying to navigate 4 levels deep to find how to apply a
CSS border to something (see #2 above). Not that DW's can't be as well, but
generally, I find it much easier to find things.
5. DW's nomenclature for HTML stuff is more standard 'compliant' than
FP's - not that this would make any FUNCTIONAL difference. But try finding
a "watermark' description on W3C's site. 8) Both programs have goofy stuff,
though.
In fairness, there are areas where FP is much better, too -
1. FP seems more geared to those who have no prior HTML experience and who
have no real intention to learn it.
2. FP provides an easy way to get a site on the web - complete with a nice
theme and functional navigation - in a big hurry. If that's what you are
about, then FP is perfect.
3. FP seems to have a better relationship with other Office Applications
(and why wouldn't it?), although DW is very good about file compatability in
this regard.
4. FP has many more "wizards" to assist you with creation of various site
capabilities, e.g., form processing, guestbooks, etc., than DW does. In DW
you are 'on your own' to add such functionality.
Again in fairness, you can build a smashing website with either app - in
fact one that has no 'footprint' from either program.
That's just my take on things, however....
