Some would argue that the 7 is the best, while others would go for the 6, 5, or 4.
Best is purely a matter of opinion.
Personally I have found the 5C to be lacking. It's not the best for scuba diving and is useless for knocking nails in so in my job as an underwater construction worker, it fails.
Question for you. Best for what?
is iPhone 5c is best to use have anybody experienced?
