BBEdit for raw code work.
Adobe GoLive for WYSIWIG work.
BBEdit is just a great tool for dealing with code. Really fast and never adds anything to your code or changes it.
GoLive is really easy to use with great site management. For doing adult type sites I don't use any of the advanced features since I want simple easy to edit code, but for mainstream sites that I don't care what the code looks like I will use them. Also it integrates really well with other Adobe products.
I've used DreamWeaver but it just keeps on getting in my way and kills my creative process.
