Adobe for Glossies; Macromedia for the Web
As a professional web designer, I have always preferred Macromedia products (geared for the serious web designer). Macromedia was (and still is) the best programming for all kinds of internet users (dial-uppers included).
Macromedia's Fireworks was definitely designed with web-related designing in mind.
Adobe's Photoshop has been traditionally geared towards graphic design - not web design. When Adobe came out with Photoshop 5.5, they also released it with ImageReady (a sucker like me thought I should be versatile). Macromedia still came out better for me - as a web designer.
Unfortunately, Adobe bought Macromedia. Currently, Adobe has no real competitor(s) to keep 'em on their toes.
Just my two cents.
