That a bold statement your making here ...
There is one thing I will tell you that Sprint have a roaming agreement with Verizon so Sprint users can roam on Verizon network therefore making it look like Sprint have much more coverage ....
BUT .... there a down side to it ....
If Sprint users roam on Verizon too much then Sprint will cancel and close thier account without any ETF because each time a Sprint user roam on Verizon the Sprint have to pay Verizon for that roaming usage and it cheaper for Sprint to close account on users whom roam too much.
Same with Verzion user roaming on Sprint network but Verzion have much more coverage and towers than Sprint so Verzion users don't roam as much Sprint users roams
There been college students who lost their Sprint account because they go to college where there no Sprint service but only Verzion same with Army people who go to Fort in another state have no Sprint service etc so they get cancelled for roaming too much.
