Fireworks v.s illustrator?

For creating a website, Fireworks is better than Photoshop because it is light weight and handles the web designing tasks. But you can use both to handle edit and create web graphics.

i like to use all of them depending on the project, their all equally powerful, though from experience id say that fireworks is more focused on web development, however i find photoshop the easiest to use since i started with it
