What is Better Iphone 5s or 5c?

Define "better"

I'll bet you're not new to Google... http://lmgtfy.com/?q=5c+vs.+5s

Why don't you take a look here and make your own assessment?

Feature-wise, the 5S has a little more to offer and the body is a little sturdier.

5s was the more expensive flagship phone

5c was the cheaper but in more colours model

I would prefer the 5s myself, far better case and sturdiness. But looking at them first is the best way to decide.
