Differences between Iphone 4s vs 5s?

So I know that their are some obvious differences between the Iphone 4s and the 5s. I'm going to be switching to Verizon soon, and I'm able to get one now. So what I would like to know is, is it worth it to spend the $200 to get the 5s or the 99 cents ( with 2 year contract on both) to get the 4s. What differences would make it a deal breaker on either end? I like to use my phone mostly for streaming video and taking pictures, and obviously calls. What are the major drawbacks on both models?

Added (1). I can afford the 5s, but i just want to make sure its worth it

5S is worth it but ONLY if YOU can afford it

Basically the size of the phone, camera, battery just to name a few. Hope this helps a little.

Don't bother getting the 5S, it's better, but not by much. Just a little faster. If I were you, I'd get the iPhone 5. The 4S is cheaper and smaller, but thicker. I prefer 5 though.

Hardware is a 100 times better on 5S, its not even close.
