Photoshop is more advanced and has more tools.
Photoshop has a wide range of tools, which allow you to manipulate or create your own image. You can crop, rotate, change the colour or style, and plenty more useful tools. It's ideal for touching up photographs. There are different types of selection tools that are great for just editing a certain area. the best way to understand photoshop is to open an image and then play around with each tool individually, and get a feel for what it does. If you need help on a particular tool i can try and explain how it works and what it does. Note: Photoshop works in layers, which are very handy once you've made sense of them. i hope this is of some use :)
One of the most touted new features of Photoshop CS5 is the mini bridge. There are also improvements to content aware healing and content aware fill. Both of these latter tools are useful in removing unwanted objects from photos, or filling in open areas.
It is question for Photoshop and Illustrator developers, which tool is from which app but Illustrator have Photoshop raster filters, that's for sure.
In Photoshop go to File > Automate > Photomerge, from Adobe Bridge go to Tools > Photoshop > Photomerge.
