From what I've been reading, according to Consumer Reports testing, the HTC 1 M8 bends easier than an iPhone 6. And the iPhone 6 bends easier than the iPhone 6+. So there you go, just don't sit on your smart phone, not a good idea *smile*.
I couldn't get myself to buy an iPhone 5 or iPhone 5s due to the lack of features, especially the display size. At that time, I felt that Android had passed iOS in features, and the iPhone 5 was a non-starter for me. I had an iPhone 4, and my Verizon phone upgrade came up, and the iPhone 5 came out with that mini-screen, and the feature set of the past, I went to the Samsung S3 as my next phone instead of the iPhone 5. Although iOS 8 has improved that a bit. I still can't see using a phone with a screen that small anymore.
That's just me though, some people think that the iPhone 5/s is just the perfect size.
