Hi, I own a Iphone 4. I don't like the orange peel effect of my Phantom Skinz screen protector and I was impressed by pictures of the SGP screens. I see many users seem to recommend the Oleophobic one. I was wondering which of the 3 (OP, FINE (anti-fingerprints) or CRYSTAL) is best. Why ? Anyone compared two or more and found a definite favorite ? Thanks !
