What's better iPhone 4S or 5?

I'm looking into getting my first smartphone. My budget is low but with the $50 off at Best Buy I'm excited to get one! I've looked into both Android and Apple, and I want an iPhone. Does anybody have an opinion on which is better and why?

Well, 5th generation is better if you need speed or if you want it to stay "IN" longer (before it is outdated).

If you are low on money, and might not be able to afford the couple hundred dollar iPhone (iPhone 5), then the iPhone 4 is better, it still works alright, and can have all the apps, it just is a bit slower.

The 5 of course.

Faster, slimmer, lighter, more powerful iPhone. The best one they have released.

Some people just scratch the surface & say it is just a taller iPhone 4S when there's definitely more to it than that.
