They both have their uses, Just depends how much you're willing to spend, especially if it's just a hobby. But if you're going to do Professional work you generally need to have Photoshop. Photoshop CS has an image size limit of 300,000 X 300,000 pixels and 56 channels per file. Photoshop 7 is at 30,000 X 30,000 & 24 channels. Remember, Print files can get mega-huge. CS can support non-square pixels for those that work with video. For photographers there's an improved histogram, and built-in camera Raw format reading as well as a great new shadow/hilight adjustment menu. Visit the sites, look around for reviews, take the trials for a spin... figure out what's best for you. Perhaps 1, perhaps both, who knows.
