Planning to get an iPhone 5?

So I'm planning to get a iPhone 5/5c/5s (I don't know the difference between them). I just want to know the pros and cons of having one. Right now I have the first galaxy. It sucks. So give me just the main thing on iPhone 5, pros and cons, and what the difference between all the names of it, ect ect ect.

The iphonr 5s is different colours and the iPhone 5s is said to be better as it is smaller than the IPhone 5c, it has a better camera and has more chips than the iphone 5c. The pros and cons are:
pros - its fast, light yet sturdy, the design is good, perfect sized screen, good battery.

cons - the backing is easy to gain scratches, the maps is not always correct, the lightning port is making you get new chords (the charger is very small) , the apps aren't always ready when you first get the phone, it hasn't got siri i don't think?

overall - apple kept its promises. They said they will give us the iphone 5 with better battery life, bigger screen and a faster phone and its got all that! X

The iPhone 5 was discontinued so that's out of the question.

The iPhone 5c is basically an iPhone 5 with a plastic body. It's $99 on contract.

The iPhone 5s is has the same body as the iPhone 5 but it has an EXTREMELY nice camera/flash, and it's about 2 times as fast as the iPhone 5c. Plus the 5s has a fingerprint sensor so you don't have to type in your password. $199 on contract.
