I've used Rapid CSS and HTML pad, and now trying webbuilder. Very impressed, but it's still not the dreamweaver killer I hoped for, and won't be until it provides a few all too critical site manager tools.
One of the greatest values I find in Dreamweaver is that I can move files around and Dreamweaver will update ALL the absolute or relative links almost flawlessly. For this reason alone, I cannot part with dreamweaver, and I would bet I am not alone. Reorganizing a big site is just too much work manually without such managers.
I also wish this product had such a powerful site manager, and Secure FTP, so I could use mature hosts which insist on secure FTP.
All in all, a great product.
