i've used the spigen glas.t (original) ever since it came out. about a few months ago, i dropped my phone and it hit the corner (edge) of the protector and it created a nice crack on it.
i decided to try out the bodyguardz pure since i got it on sale from amazon. it's pretty much the same thickness as the original glas.t. i heard great reviews about bodyguardz and some even said it was better than glas.t.
however, i have to say, i totally disagree about bodyguardz being the better screen protector.
IMO, the glas.t was WAY better than bodyguardz. i have earrings (diamonds) and the glas.t seriously held up from being banged by my earrings... aside from the crack, the rest of the screen was pretty much pristine.
the bodyguardz on the other hand, i've had for maybe 3-4 months (maybe less), and there's already a ton of micro scratches from my earrings, and other scratches from daily use (i don't really abuse my phone and seriously, i was really disappointed with bodyguardz especially after coming from glas.t). also, i felt that the glas.t's oleophobic coating is a lot better than bodyguardz.
the bodyguardz protector's coating seemed to have already lost most of it's potency. it's unfortunate really. even tho, i'm part of the bodyguardz program where i can get a replacement protector for cheap, i think i'm gonna have to go back to glas.t when i decide to replace my protector.
i know spigen has newer, slimmer ver of the glas.t and i just hope it has retained the same quality as the original glas.t.
tl:dr - glas.t
