lets see... it really depends on what graphics you are making... if you making simple nice little graphics, like some text on top of a single color button or something like that, then get the Macromedia package. Fireworks is good for simple graphics... i personally never really liked freehand and dreamweaver (3 at least in my experience) tends to add a lot of extra tags to the html that its writing, but nevertheless, is a pretty good program...
If your making/manipulating photos, get Adobe. However Illustrator and Go Live! are pretty useless to me.
Personally, I like both companies products for their own reasons... For the "ultimate package" I would just suggest getting Macromedia's Fireworks, Dreamweaver and Flash 5 (if your interested in web animation) and Adobe's Photoshop 6.
Heres a hint though, if you DO get Dreamweaver, it will help you out quite a bit if you teach yourself HTML as well so you can tweak the dreamweaver code. Sometimes it'll put extra code in and stuff thats not compatable with Netscrape, or even put certain tags in the wrong spots (like when assigning a background image to a cell of a table, it will put it in the TD tag instead of the TR tag... quite annoying)
