A week into my wife owning an iPhone 6s plus and, let me tell you - it's on a different planet than my flagship android, the s6 edge. The iPhone feels like a solid object, like something crafted vs something pieced together. Evertyhing works without a stutter, and the pieces of the ecosystem work fluidly and with such grace - plug in the usb in my car and, boom, carplay launches. Apple tv airplay? Just works beautifully. There's just a perfection of execution that android kids don't get, and it's worth a premium to me (but I'm not really paying a premium, my monthly charge is the same for a samsung flagship or apple flagship).
For example, I know android had live wallpapers first but the execution was something out of a 1990s video game, while apple's execution feels vivid, 3d, and really "live" - it's futuristic and slick. Find my iPhone works all the time, my android doesn't work if wifi's sleeping (it shouldn't, but it does). It's like the different between a casio and a hamilton (i didn't say rolex, i'm trying not to be pretentious). One tells the time, the other tells the time as well but make sure the pieces all fit together with more care and precision. To compare the iPhone 6s to something like an LG is absurd, they're just different in ways that have less to do with specs and more to do with attention to details execution.
