In your opinion, for users like yourself.
When two substances rub together, the harder one ablates the softer one.
Keys and coins and steak knives are typically softer than hardened glass.
Quartz sand, something I encounter daily, is very hard.
Corning does not say that GG3 won't scratch - they say that scratches are "less visible" with it.
"Scratches are less visible" - Corning's words, not mine - sounds pretty subjective to me.
Maybe less visible than with GG2 or soda glass (why they bother to compare to that escapes me but oh well) - but is it less visible to the point that I'd find it acceptable??
The key-scratch tests, steak knife tests, and the rubbing with a piece of concrete test really don't impress me. Might as well compare to cotton. You can look up the chemical properties and predict the winner.
Show me the results of GG3 with quartz sand used against the glass, then I'll be convinced.

Casual and normal contact for many of us involves hard sand - something that those of living in the Southwest or living near the Great Lakes find more commonly than others.
Your mileage may vary, normal contact for one person is not normal contact for everyone.
