I think the reason Apple came out with 2 iPhone 6's this time around is because they couldn't make up their mind on which size to go for.
What they should have done really is gone 5" and put the OIS camera and the possible 2GB of ram into the 5" version while also adding a 1080p screen which would have had around 445ppi hence slightly sharper.
That way they would have had best of both worlds, phone roughly around the size of the S5 or HTC M8, while still having a big screen to please everybody that wanted a larger screen iPhone this time around.
The 5" iPhone 6 would have been the Goldilocks size that would have near enough suited everybody that wanted a bigger screen.
