I use zend combined with filezilla. I also have dreamweaver on my computer at work, and I use it for doing my CSS coding due to the auto-complete features on it. But I don't like the built in ftp - its slow, and you can't work while its up/downloading pages. I find filezilla significantly faster. And since I am working in php 99% of the time, the design view doesn't do anything for me in dreamweaver anyways.
