Should I upgrade to the iPhone 5S?

I'm due an upgrade soon on my contract, 4th November to be exact. I own an iPhone 5 at the moment, but this looks truly irresistible! I want it so much? Any advice would be a great help!

Iphone 5s is a great phone

Depends on use, if its just for calling and texting and internet then basically your paying apple for minor hardware tweaks and giving your fingerprint to them

Any advice? Learn to control yourself.

All phones are the same.
