When i first tried it, it seemed better. Fingerprints don't stick well and are easier to remove. After using it for 4 hours though, this is what happens. The grease sticks differently to the surface. While its not so easy to get it to stick, as soon as its on its harder to wipe of. The 2G has a glass that actually feels like a glass, its colder too. The 3GS seems more plastic like (only relatively). The grease defintely becomes more hazy on the 3GS screen, when looking at it from an angle, rendering it harder to read and especially under direct illumination (like sunshine).
