Is it better to get an iPhone 5 or 4S?

I'm thinking of getting an iPhone later on in the year. I don't know whether I should get the 5 or 4S because everyones saying that the 4S is a better phone but the 5 is newer.

Samsung GS3

The 5.

The iPhone 5 is obviously better because it has improved features of the iPhone 4s. If you can afford it, and want the bigger screen, new design, 4G and faster processor, then maybe you should get the iPhone 5
