It is so not. It adds so much bulk and looks ugly. I wouldn't mind if it were thin but ugly or bulky but not ugly. But the two together just make it worthless. How is it the best case when you have to remove the screen protector to use it? Also, unless you drag the iPhone 4 on concrete or diamond, the glass won't scratch. You say it is very prone to scratches, any pictures to prove that? If you know what the glass is made of, you won't believe in this silliness.
Best case so far is Apple's Bumper. It doesn't scratch the metal band like some people say. I've had it on for about over a month. I'm currently using the SPeck PixelSkin HD which is also a good case.
