What's the difference between the iPhone 4S and 5S?

I have an iPhone 4s right now and my 2 year contract is up in a week. I really like iPhones and was thinking about picking the 5S as my next phone, but what are the differences between the 4S and the 5S? Also, if anybody knows, what's the difference between going to a Verizon store and the Best Buy Mobile store? Are there any price differences or anything?

The iPhone 5 is much longer than the iPhone 4 and the iPhone 5 also has iOS 7

5S is far better hardware, not even close.

Could compare the 2 at GSMArena.com
