Here’s where Spectrum really starts to pull away—it’s much more widely available than AT&T, especially in rural areas. This is largely due to fiber networks still being built out—providers typically start in larger urban centers. Cable, on the other hand, is more widespread and already exists in many spots.
AT&T’s availability is mainly concentrated in the Southeast with a smattering of coverage in some Midwestern states, like Kansas and Oklahoma, as well as a bit in California and up near the Great Lakes.
AT&T’s DSL service is more widely available, but the company no longer offers this service to new customers. For this reason, we aren’t factoring this availability into the equation.
Spectrum is more evenly distributed around the country, including some spots in the Pacific Northwest and New England. It offers coverage in a number of states that AT&T isn’t in at all, like Colorado, Nebraska, Maine, Montana, and Oregon.
