Dreamweaver is a combination of an IDE for PHP, ASP, ColdFusion and a WYSIWYG HTML/CSS editor
I had previously used aptana 3 for a couple days and may have come to the conclusion that it is better than dreamweaver at actual html css coding
Code Hinting with CSS in Dreamweaver 5.5
Id go with dreamweaver because is has the design view as well as the code view;aptana is more for developers rather than designers and developers
Dreamweaver vs aptana studio (for those who don't know coding)?
