I voted Verizon as well, have them right now, its the best coverage iv'e ever seen tbh, my friend has TMobile and can rarely ever have any data connection.
Speeds depend on location, as in my house I get about 15MBPS on 4G LTE, but in a lot of other areas I get 35+ MBPS
I also got 10GB per month for crazy cheap, so yeah..
Also, please don't get AT&T, they have crappy customer service..
