Important Information About the Coverage Map
Map may include areas served by unaffiliated carriers, and may depict their licensed area rather than an approximation of their coverage. Actual coverage area may differ substantially from map graphics, and coverage may be affected by such things as terrain, weather, foliage, buildings and other construction, signal strength, customer equipment and other factors. AT&T does not guarantee coverage. Charges will be based on the location of the site receiving and transmitting the call, not the location of the subscriber. Your phone's display does not indicate the rate you will be charged.
Note: Please carefully review the Plan Terms, which explain the limitations of your service. Service is not available at all times in all places.
Straight from Verizon's coverage page:
These Coverage Locator maps depict predicted and approximate wireless coverage. The coverage areas shown do not guarantee service availability, and may include locations with limited or no coverage. Even within a coverage area, there are many factors, including customer’s equipment, terrain, proximity to buildings, foliage, and weather that may impact service. Some of the Coverage Areas include networks run by other carriers, the coverage depicted is based on their information and public sources, and we cannot ensure its accuracy.
Sprint's page just talks about how estimation is not an exact science and weather and terrain effect coverage...nothing about including other networks.
Decided to quote because it's not fair not to since I did for Verizon.
Our coverage maps provide high level estimates of our coverage areas when using your device outdoors under optimal conditions. Coverage isn't available everywhere. Estimating wireless coverage and signal strength is not an exact science.
There are gaps in coverage within our estimated coverage areas that, along with other factors both within and beyond our control (network problems, software, signal strength, your wireless device, structures, buildings, weather, geography, topography, etc.), will result in dropped and blocked connections, slower data speeds, or otherwise impact the quality of services.
Services that rely on location information, such as E911 and GPS navigation, depend on your device's ability to acquire satellite signals (typically not available indoors) and network coverage. E911 services also depend local emergency service provider systems/support. Estimated future coverage subject to change.

Conclusion: Besides for Tmobile, they're all pretty much on the same exact page.
