Then look at the non apple benchmarks.

4 -> 4S: Camera and Siri. Yawn. Half of people don't use Siri.
5 -> 5S: vastly improved camera (two tone flash makes a world of difference), TOUCH ID. I don't know why people are downplaying the touch ID. Probably its hard to see the big picture of touch id and what it will lead to in the future.
TouchID... Who knows when (if?) Apple will open it up to developers. Until then, it's a big yawn. Omg I can unlock my phone one second faster! Until my banking app, amazon, eBay, Starbucks, and PayPal etc can use it, it's all hype.
Returned my 5S and looking forward to the bigger screened 6.
