IPhone 5S vs iPhone 6 vs iPhone 6 Plus?

I'm a college student with a lot going on regarding technology. Regarding that, however, I'm not nerely as extensive of a phone user as the average youth, therefore I don't consume battery life as extensively and charge overnight. I text/call/listen to music a lot, every so often check Facebook and Snapchat, and sometimes browe the internet. That being said, I'm looking for something that will fit my needs of average usage. Which phone would be the best for me?

None of the iphones for sure. They are just overpriced. Look into the phablet market, get a Xiaomi Redmi Note maybe? Or if you prefer something smaller, the Asus Zenfone 5. Those phones can handle anything thrown at them (except pretty 3D games.) with ease and are rather cheap at ~$200.
