Is the iPhone 5s worth investing in?

I'm debating investing in a new smartphone, I'm in a gridlock between the iPhone 5s and a windows cellphones. I've looked at the specks for several phones however the iPhone seems to have many of the tech treats I'm looking for, however, is it worth the 600$ or would the iPhone 5 suffice?

You have to make up your mind about software and which UI you want to use. I much prefer iOS vs windows phone (I prefer android over all). Once this decision has been made, you can much more easily look into hardware. Now if you are talking about buying the phone straight out, you are going to pay around $600 no matter what. The 5 is discontinued on apple's website but you can buy it on amazon for around 600 still. The 5s is $650. YES the 50 dollars is worth it.

5S rocks.
