Should I get the 4S or a 5S/C?

My dad told me that he'll be getting me and my brother iPhone's during the summer holidays. I'm starting college soon, and as sixth form life requires responsibility I thought the more mature decision was to buy a used iPhone 4S and sell it on later when surplus to requirements.

Should I get the 4S nor or wait until my dad actually get the 5S/C. What is better in your opinion, a 5S or 5C?

The 5S is the best iPhone due its specs and features, however, the 4S and 5C are both great. The 4S is getting old and won't be worth a lot of money in the future, so I wouldn't really recommend it, but I highly recommend the 5S and 5C. If you like bright colours I recommend the 5C due to its different variety of colours it comes in, but if you want a phone that is a little faster and like the idea of a finger print scanner, go with the 5S.

The 5S is the best now, very soon the 6 will be out. I'd stay away from the 4s as the upgrades to to IOS have already slowed down the 4's a great deal and when the new IOS comes out I'm not even sure the 4's will support it and if they do, they will be too slow.
