Is it worth getting iphone 5s over the iphone 5?

I have had the iphone 5 for a while but I want the 5s now. Is it worth getting?

Unless you really care about the fingerprint scanner, I would say no. Another option is the 5C. Personally though, I would recommend a different phone such as the HTC One M8. It has much better specs and costs about the same. If you're looking for a smaller phone, you could go with a Mini version of a Galaxy phone (S3, S4, etc.)

Yes it is!
The iphone 5s has a 64 bit system instead of a 32 bit which the 5c and 5 have.
5s has a much faster processor.
5shas a fingerprint scanner on the home button
5s also has M7 coprocessor which can tell you your speed when driving and your sleep schdule from the movements of your bed,
5s has a longer battery life than the 5 but the same as the iphone 5c,
5s front camera is a little better than the 5 but the same as the 5c,
the back camera on the 5s is a little better than the 5c and 5.
the 5s has slow mo and burst mode for the camera and video.

so the 5c and 5 and pretty much the same thing the only difference is the 5c comes in colors and has a slightly better front camera and a longer battery life

even though it is twice is price the 5s clearly wins being a better, faster phone which is very fast and has lots of extra cool features

The iPhone 5s is an upgrade, but if you were wise to would wait for the iPhone 6 to come out (probably fall of 2014)
