For us if you only stay near the Interstate Roadways or large cities almost any of them work. If you want to get way back off the roads then Verizon was always the best coverage... Even works in rural ALA and MS
All of the providers have very active coverage at different places. All depends where you are...
The seller for me was my working years that took us to all parts of the USA working on DOD Electronic Systems. Verizon was best thumbs down...
Verizon seems to not have the best deals however...
Just my thoughts...
