Reason 2: App associations are under your control
Unlike iOS, you get to pick which default application is used for several core functions. I personally prefer Chrome as my browser, due to cross platform syncing, and have it set as my default web browser.
Reason 3: Visual task switcher
I like that I don't just see an icon for a recently used/open application, but get to see the actual status of apps I want to switch back to in the HTC visual task switcher.
Reason 4: What do YOU want to do?
Android gives you the power to control what you want to do with files. As you can see in this screenshot, there are a number of things you can do with an image in the Gallery.
