I cannot say much about sturdiness - although I have had Honda OEM windshields that withstood impacts far better than the insurance sanctioned "OEM replacements". I was told by autoglass specialists that Honda's windshields have "2 to 3 more stranded layers" which makes them stronger than the average direct replacement.

Additionally, I believe the angle of impact is a major determinant in how likely the windshield will fracture. Since the HCH-2's windshield is so sloped, it may very well be that any rock or similar debris will likely be deflected or "roll" over the body. On the other hand, the windshield is also larger and depending on the outside temperature its coeficient of elasticity may be very low and hence still crack.
