Best mobile phone network in OKC metro?

[TheTravellers]

Not looking for best mobile-phone company, but just the network. Currently have Virgin Mobile, which uses Sprint, and it's been quite acceptable in OKC and suburbs, as well as most other areas we've vacationed to, but had no-to-crappy service in Guthrie this weekend (yes, actual spots in downtown Guthrie where there was no service), which was weird. Historically, I know AT&T and Verizon are some of the older, better infrastructures here, but not sure how good anybody else is (thought Sprint was good until this weekend, ha), and thought I'd ask the masses since y'all are way more educated about mobile phone stuff than I am (had an original Razr until about 9 years ago and then switched to an HTC One, which I still have, but is getting pretty long in the tooth). Thanks...

Just realized that my HTC One is only 3G and any new phone (which I will be getting in the next few months) will be 4G and will probably be way better coverage-wise than 3G, so it may be a moot point.
