I don't care for screen protectors either since they get scratched up fairly quickly and never have the same premium feel that the bare screen provides.
Since my phone spends a fair amount of time in my pockets with other things stuffed in there with it I was always afraid to get scratches in the screen itself. I tried the glass screen protector for the first time with my Note and am sold on them.
I don't know what Spiegen makes them out of but there isn't a loss of resolution nor has it ever been scratched. A couple of added bonuses are that the home button is slightly recessed (no more screen turn ons inside of the pocket) now and even with the protector on their Neo Hybrid still has a lip on it so your screen isn't touching when you lay it flat on its face.
That's always been my complaint about screen protectors and I've pontificated on it to no end. Why on Earth would you put something on beautiful screen that makes it look less beautiful all the time to protect the beauty of the screen? I've never had luck applying them without bubbles, but that's on me, not the overall concept.
Also, you're braver than I am, as I've carried my phone in my front left pocket by itself for years now. Everything else (except my wallet) goes in the right front pocket. Keys, change, chapstick, smokes, etc.
On very rare occasions, I might let my pack of gum go in the phone pocket, but always on the backside of the phone, even though the chances of the soft cardboard of the pack has almost NO chance at scratching the glass.
Also, I trust Gorilla Glass after having seen version 1 of it intentionally scratched with keys to show its effectiveness. They've only continued to improve upon the product since that video, but not everyone is as cautious with their phone as I tend to be, at least as far as carrying it around goes.
In closing, I suppose you get what you pay for as well. There's a chance that, if I spent a little extra on a "good" screen protector, I might like it better, but my original points stand as far as my preference.
