My top three phones are:
1) iPhone 5s
2) My current iPhone 6
3) HTC One M7
My favourite is easily my iPhone 5s. It looks better than my current iPhone 6, it felt more premium in the hand, it was easier to use and fit in pockets better. The only good thing about the iPhone 6 (apart from the obvious internal upgrades, like CPU etc) is the screen. I don't think the 6 looks or feels anywhere near as premium and well designed as the iPhone 5s. I actively dislike the look of my iPhone 6 but love the larger screen (which I need). I wish the 6 had a smaller bezel and was not as thin as it is, which would have allowed for a camera that didn't protrude. I'm not looking forward to the iPhone 7 if the rumours are true.
