I'm a little surprised and disappointed Apple have went for the big phone/phablet.
I'm one of those twirps who enjoys a phone thats ~4.5 inches screen and easily used with one hand. Apple kept the flag flying, and I'm pretty sure the wee flagship Android phones wouldn't exist if they had bailed on the small form factor much sooner.
As for Android specs superiority vs Apple, console war type fare, but I believe one of the defining characteristics of Apple is the unification between its platforms, and the expectation that when you buy their hardware, their software will be tailored to maximise performance (iOS updates have negated this slightly, but it's not a dealbreaker)
It's an apples (ha!) and oranges debate really, when I think about Apple, I don't think about constant device tinkering, jailbreaking and such. I think of a pristine user experience and well designed hardware. When I consider Android, I'm basically keeping notes of specifications and OEM history with allowing unlocked bootloaders/rooting. It's funny really, it invalidates a lot of reviews from tech sites, because a lot of complaints stem from OEM software quirks, all of which can essentially be ignored if a phone has a vibrant developer community behind it.
I'm just very happy they both exist. I love my iPad, I love my Z1 Compact. Let's all just put our hands down each other's trousers and synergise.
