I use both daily for work. I am very used to both, and each have their strong points. Generally, Fireworks is better with optimizing the output for the web, while Photoshop is superior for print work. You cannot go wrong with either though. Simply choose the one that is easiest for you to learn, or get both if you have to use it for business. Some methods are easier in one program than inthe other, but just about everything can be done in each.
