Difference between the iPhone 5's?

So I'm ready to upgrade my phone and I'm curious about the different iphone 5's. I honestly don't know the difference but I do know that I want the phone with the best quality (as in durability). I'm not really into all the cool gadgets that comes with each phone, but I do wanna know the major differences between the 5s, 5c, and 5. I heard one of them breaks easily or has battery problems but I'm not sure…

5s is the latest

None its a great phone

The 5S is the most powerful. The 5C is pretty much the same as the 5 but with a plastic case. Considering how flimsy normal iPhones are, it's probably just as durable as the others. And the 5 is the first that came out and is somewhere in between the others.

Advice though, go with a android smartphone, if you look at the actual hardware of iPhones, you'll see they are way less powerful and Way more expensive than Androids. The LG Spectrum 2, for instance, is free with a 2 year contract and is twice as powerful as an iPhone. But if you're Really set on Apple, get the 5S if you have the money.

5s is much smarter one. You can't compare 5s with any other
