I could also say I love the pure screen protector, it feels amazing, I'd say it feels like the original glass of the phone if not better, fingers slide across nicely. I too have never tried the sgp though for comparison however I don't think I need to after using this one. I would definitely buy this again, I would almost never go back to a plastic screen protector or zagg crap. Install was quite simple and easy, and I am one of the worst at installing screen protectors. Also the finger resistant coding seems to be holding up in my experience. I have not yet seen a finger print or grease mark on my screen, but I'm also gentle and wash my hands frequently, especially before touching my phone. Overall I'd give this screen protector a good recommendation. The only negative I could probably find is that the glass is quite thick, you can definitely feel it when you touch the home button. But I feel like my finger fits nicely into the home button spot, gives a little added grip. Great glass screen protector, a must have!
