What is the better buy for Iphone?

So, i was looking for an IPhone to buy, but i'm not sure what's better IPhone5 or IPhone4… I [want] a black Verizon one, with good internet & a good camera (or at least a reasonable camera). I have been told the prices, retina display, camera/video, and data storage were changed from the 4 to the 5. Please, give a reason y one is better don't just say "The IPhone5" and thats the end of it.
Tanks~!

The iPhone 4 would be better if you want to save money and the iPhone 5 would be best if you want to keep up to date (remember iPhone 5s is coming soon)… I personally didn't see alot of differences between the iPhone 4 to the iPhone 5 other than the fact that the 5 can play games much smoother and better. The camera for the iPhone 5 is 8megapixels which is great but my iPhone 4's camera with 5 megapixels can compete with that. But i have a feeling youre going to like the iPhone 5 more so if you can get 199 with 2 year contract then i recommend that but for full price its not worth it
