IPhone 5s and 5c cameras in comparison to the 4s camera?

I own an iPhone 4s. The camera is pretty wonderful aside from the front-facing camera, but I improve those photos with an app I bought. So I was wondering, for those of you who are experienced iPhone users, if the 5c or 5s iPhones had a better camera than the 4s I'm currently using?!

I don't see much of a difference i have the 4s like you my daughters have the 5s

5S is far better, its not even close. It also has burst mode, low light photo taking, and slomo videos.
