Should I go with t mobile or verizon?

IIm in a pickle. I can't figure out which is the better option/ deal for my situation. I live in California 93436 area. The 4g lte coverage is great with Verizon in my area. For t mobile I live on the edge of a 4g lte and 3G coverage area so I ll get both intermittently but at least I have Wi-Fi at home so it's okay. Verizons deal is two lines sharing 10gb on the edge plan for two iphone 6plus for 186.00 a month and you pay $138.00 tx upfront. T mobile deal is unlimited 4g lte (throttled at 21gb) with 7 gb personal hot spot and free music streaming for each line that is 162.00 a month and you pay $314.00 for two iphone 6plus upfront.
IIm confused bc t mobile seems like the better deal but could have crappy coverage but verizon has good coverage but only 10 gb but less upfront for the same phones. IIm do confused!

I would go with Verizon.

Only you know what you can afford to pay upfront. In the end you will be paying full retail for the phones by the end of the 1 to 2 years you will be paying for them by installments.

So the thing is, which carrier where you live, work, commute and spend your time in, has the best coverage for each carrier? Try both out with a pay as you go phone/plan and see which one works best for your needs. Is this a hassle? Yes but better to have a little hassle for a few weeks, than the complain about it for 2 years.
