So when I first bought my Surface Pro 3 I bought the Microsoft Tempered Glass Screen Protector. It was awesome and couldn't tell it was there. Well the other day it cracked so I took it off and have been using it without the screen protector and did not realize how much smoother and easier everything is without it. Games respond more better without the protector , (I.E. Spartan Strike) I haven't had to rewrite handwritten notes in OneNote anymore. I feel like the screen is just as protected now as it was when I had it on. I am very OCD when it comes to my tech stuff, writing straight on the screen is and not having touch points missed really made my surface feel so much better.
