Is the iPhone 5s a good option fot buying on 2015?

Do you think I should buy the iPhone 5s? Or is it going to be too old next year? Just as iPhone 4 and 4s?
I also may buy the iPhone 5c. Same question goes for that
Give me your opinion please.

Its fine. Effectively its currently the 2nd best iPhone available today (would be 3rd by year's end)
