I have an iphone 4s and I'm debating whether to get the Iphone 5s or the 6?

I personally like the look and design of the 5s better, and from what I hear, screen size and size in general are the only big differences between the two phones. If I were to get the 5s, I would get my dad's current phone b/c it's only a few months old, and he would get the 6. Then I would be able to get the 6s when it comes out, because his contract would be up by then. What do you think?

Recently had my iMessage connected to both my iPhone and MacBook. I switched my iPhone 5 to a 5C today, and now my iMessage isn't connected interchangeably to both my new phone and my MacBook. Messages that I'm sending from my Mac aren't showing up on my new phone, but still my old phone. How do I go about changing that so they will show on my new phone opposed to my old phone?
