I only use the "Code View" in Dreamweaver (color syntaxing for PHP, (X)HTML, CSS, Javascript, etc.) for coding, Macromedia Fireworks for graphics, Photoshop CS2 for photo editing, and Apache/PHP/MySQL running on my local computers for testing. The best thing about all these programs is that they are all Windows and Mac compatible, and Macs even come with Apache and PHP already installed.
But of everything, the best possible tool is you and your team. Together, come up with creative and innovative solutions. Make a high-quality website that is truly your own, that your team (and your team's grandmothers) would be proud of. Ultimately, any software you use is just a tool to help get you to your goals faster; all the real work and creatively is going to come from the pinkish blob in your head.
