What is the difference between griffin and armored iPhone cases?

What is the difference between survivor griffin iPhone 4 case and survivor armored iPhone 4 case? My niece wanted a specific color griffin case but I can only find that color in a box that says armored and doesn't say anything about griffin even though it looks like one. There even the same price. Is there a substantial difference?

Griffin makes several types of cases for the iPhone. There are the regular light duty cases, which come in a multitude of colors, and the Armored Cases, that are heavy duty and come in a small variety of colors.
