I'm using the TechArmor Ballistic Glass. I would give it a 10/10. TechArmor claims it has above a 9H hardness. While I cannot attest to this I can tell you the glass retains all of the sensitivity of the bare screen and is silky smooth. Be aware that due to the nature of the iPhone 6 Plus' screen being rounded any tempered glass will not extend to the edges of the iPhone. Installation was easy and quick. TechArmor provides detailed directions which I advice you follow. They also have videos available to help you. I almost forgot about screen clarity. Clarity is 100% for 99.99 percent of the screen. The very edges of the glass protector show color prism (for lack of a better term) when held at certain angles. This has not been a distraction for me but is noticeable. I still give this product a 10/10. Hope this helps. Let me know if there is anything else.
