The technology has been protecting a wide variety of phones for years now, but it’s not the only solution on the market. Dragontrail Glass, Sapphire, and tempered glass are all popular options. So how do they all differ from one another? Which one is best? We’ve got a few answers.
Which is better depends on what you think is most important: scratch resistance, weight and thinness, affordability, impact resistance, or a delicate balance of several of these.

We use the Mohs scale to measure the scratch resistance of minerals and other similar materials. A higher number on the scale means better scratch resistance, with talcum rated at one and diamond at 10. A material with a higher rating is also capable of scratching a material with a lower rating, such as a diamond-tipped pick scratching a quartz panel.

At this point, all major protective solutions are pretty tough on scratches. Dragontrail and Gorilla Glass seem to be evenly matched, while tempered glass doesn’t seem to be far behind at all. Sapphire has a runaway lead over all three solutions but costs significantly more.

In bending and impact tests things get much murkier. There doesn’t seem to be much in the way of like-for-like testing between Gorilla Glass and Dragontrail. Only one thing is for sure: Sapphire is comparatively horrible for flexing and dropping.
