Getting my first iPhone ever. Should I go for the 5 or 4s?

I'm going to get my first ever Apple product and I'm going for an iPhone. I'm going to use my own money so I want to make sure I make the right decision. I'm just not sure should I get the 4s and save some money or just go ahead and get the latest and greatest 5. I can afford either of them. I'm planning on having this phone for a quite a long time (3-5 years) So should I just get the 5 since its the latest model and I can afford it? I mean what's the point of buying an older model if I can get the latest one, right? Looks like I just answered my own question but I'd like to hear your opinions!

Buy iPhone 5s. Price will be low then 5. I'll come at 20 Sep

If you are sure you are going to purchse iPhone, I suggest the 4s, because there aren't any differences between 5 and 4s but the size, and the 4s costs less

I recommend you to wait for some more days n go for iphone 6/5s, far more better than iphone 5 and 4s

Latest version is obviously best
