Quick review -
I tried and used almost every type of web design software (Dreamweaver etc.) before settling on Freeway as the best available for my needs. It's unique in that it's approach is that of a graphic design program, that exports the code once you've done you layout. You don't work in code, you work in design and have the ability for advanced code as well. It offers many extremely convenient and simple shortcuts that get the job done quickly. The only real negative I can see is that clients cannot edit their own websites without owning the software and keeping an exact mirror of all the files used to create it.
