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.
 
Thre are two types of Power support. Anti Glare and Crystal. Which is better?
Since both of them contain two films, I can use one each on mine and my wife's phone right?
I am new to this forum and reading about power support for the first time. Please excuse my ignorance.

I used a PS anti glare on my 3Gs forever and never had to replace it... I did like that I didnt have to constantly wipe the screen. On my i4 I have a SGP EX Ultra Crystal set and the constant smudges do bother me but I have to admit the clarity of the screen looks great.

I have a PS front and back set on order now and might try the anti glare that it comes with for a while. If you order the front an back PS set you get an anti glare front, a clear front, and a clear back.
