Not sure if someone has mentioned this or not but from my experience the PS film seems more durable than SGP. After having the SGP for the last month I noticed with just normal wiping it seems to leave light hairline scratches and noticed a nice large scratch on the film. The PS that I have had on my 3GS since launch is still pretty much scratch free. I forgot to mention that I'm also using the SGP EX Ultra Clear. But besides that the clairty is superb. Most people doesn't even know I have a screen protector on until they see the scratch then they'll point out that I have a scratch on my screen which I tell them it's just the screen protector.
