Web development is "just coding". Web design isn't web development - it's web design. Developers shouldn't design and designers shouldn't develop. (People who can't do either one very well tend to do both.) Dreamweaver is a way overpriced crutch for developers who can't develop and designers who can't design. It's not needed by professional developers or designers, and it's far too expensive for hobbyists. (I use Edit Plus - similar to Notepad++ - Firebug and FirePHP as an "IDE". Integrating the 3 [and a web [server] - why does the site chop words? and an FTP client] creates an integrated development environment.)
I use PHPStorm and I am very impressed. I have tried nearly every PHP IDE to date and found that navigation the code is the hardest part, and the most important for the IDE to do. PHPStorm traces all calls to the code and prevalidates everything. So if you program through a lot of code, I say PHPStorm is the one. Otherwise its too expensive.
How the f*ck does Dreamweaver do ANYTHING good? It's bloated crapware with no real use for anyone - especially pros. The same thing you can do with DW you can do with a browser, a local AMP-install and a text-editor. Dreamweaver is absolute shite, and the WYSIWYG editor makes code so incredibly bad it should never see the light of day.
PhpStorm is a really good IDE. It is not free but you can use Early Access Program and you can use it without a payment (http://confluence.jetbrains.com/display/PhpStorm/PhpStorm+Early+Access+Program). I used many other text editors and IDEs and PhpStorm seems like a winner for me because it hints about many possible problems in your codebase. PhpStorm vs. NetBeans ... PhpStorm is quite similar to Netbeans but I found PhpStorm faster and less buggy. PhpStorm vs. SublimeText3 ... SublimeText3 is a really great text editor but if you work with namespaces in PHP then it is quite inconvenient. For simple scripts ST3 is enough but I got used to PhpStorm and I would not go back.
I am personally using dreamweaver and sometimes I use netbeans, But according to me dreamweaver is one of the best editor
