I want the iPhone 5 S or C, which plan/company really sounds better?

There's Verizon where I pay $200 for the 5S, $100 for the 5C, $100 each month and $2400 over the course of 2 years.

Then Straight Talk, where I pay $650 for the 5S, $550 for the 5C, $45 each month and $1080 over the course of 2 years. If I don't pay month to month and only pay every 6 months, I'd end up paying just $1000 over the course of 2 years. Which isn't much, I know.

Also Boost Mobile, where I pay $550 for the 5S, $450 for the 5C, $50 each month (every 6 months it goes down $5) and $1020 over the course of 2 years.

My biggest concern is coverage 1st, price 2nd. I can afford all three of these options. Which sounds better and which company have you heard better reviews about?

Check coverage in your area or area where you travel to often. Thats your answer.
