I prefer Internet Explorer. It's fast, reliable, and easy to use...
just kidding
In all seriousness, however, I prefer Google Chrome. Google Chrome interface is simple and easy to use. Firefox's, however, is not. With different buttons located all around the screen, I just could not handle it all. With Google Chrome, all of the buttons and programs are located at the top-right of the screen. It's effortless.
Google Chrome provides much faster page loading. It took a second with Chrome to load the main Google page, however with Firefox it took two seconds. Not a big difference, but hey, I want faster page loading! Chrome also has a tight security, which is great as I tend to find my self in spyware-infested sites occasionally.
So yeah. Chrome beats all web browsers!
