iPhone 5 or Samsung S4?

[Romayne]

I am getting a two year contract and are unsure of which one to get. The iPhone 5 is 16GB and the contract comes with 2GB of data. While the S4 is the same price with unlimited data. I have heard that the S4 beats the iPhone in functionality and features but I like the premium feel of the iPhone. I also like how it links with iTunes as I also have a macbook pro. I am an avid music listener therefore I will require lots of space for my music and I am beginning to think that the iPhones 16GB will be to small for me. I also like apps such as Instagram, Twitter, Facebook and so on. Which one would benefit me more? also for two years. And are the S4 standard headphones better than the ones that come with the iPhone 5?
