If your only measure of quality is scratch resistance, you've missed most of what makes the new screens so fantastic. They are 4 times less likely to shatter in a fall. That is hugely higher quality. The almost total lack of complaints here on this, the worlds larges forum for iPhone is testament to the durability of the new screens. Yes, to make a screen harder to shatter, makes it more susceptible to scratches. No one has yet been able to create glass which is equally harder to shatter and scratch. If someone figures that out, they'll become richer beyond their dreams.
In the meantime, since EVERY single iPhone EVER made has been able to be scratched as demonstrated by long threads on "my iPhone screen is scratched" with every phone ever released, logic suggests to protect your very expensive phone, a very reasonably priced screen protector should have been the first thing you applied to your phone.
