Sapphire vs Gorilla Glass - Bending and Impact

At 1:27, we get the straight-up answer: "sapphire is marginally stronger than Gorilla Glass, about 25% stronger, to be exact. In other words, it would take 25% more force to break sapphire glass than Gorilla."

But then things get more complicated, as Gorilla Glass is far more flexible meaning that the Gorilla Glass will likely be better.

I do wish I had a four-point bend tester like that. My guess, though, is that I would probably get in some pretty unpleasant trouble with just trying to test anything lying around.
