Durasec hightec or cleartec? I think generally the "highly durable" little more expensive ones, like the durasec hightec or the zagg invisibleshield are rubbery and as such very scratch resistant (things don't actually scratch the surface, but more like dent it, which the surface recovers from quickly), while the little cheaper "clear" and thinner ones are the usualy acrylic plastic sheet-type, which is less rubbery but gets scratched easily. I think I'll go for a 5-pack of durasec cleartec protectors.
