I've seen a lot of people complaining about the large size of the 6 Plus, but also some complaints that the 6 is not much of an upgrade from the 5/5s as far as screen size goes. Which leads me to think, would Apple have been better off making 1 new iPhone 6 with a screen size somewhere in between that of the actual 6 and 6 Plus? Maybe a 5" or 5.1" screen?
If not that, I sort of wish the 6 Plus was maybe 5.4" instead of 5.5". Since the iPhone 6 is 0.7" bigger than the 5s, it would've made sense to make the 6 Plus 0.7" bigger than the 6, which would be 5.4". I know the 0.1 inches isn't a drastic difference, but it would've trimmed the 6 Plus down just enough I think.
