Why is the Iphone 5s so much better than the Iphone 5c?

All my friends are telling me not to get the 5c, and when they tell me this I don't understand why. Is it because the 5c is made out of plastic, or is it something else?

They are basically the same. Trash.

Ask apple

The maximum storage space of the iPhone 5S is higher at 64GB and it is much thinner and smaller compared to the iPhone 5C version. It is also using a much newer and faster processor: A7 Chip with 64-bit architecture and M7 motion coprocessor.

5C is good, but 5S is the best hardware out there today.
