-The biggest knock on Google Fiber has always been its footprint. It is an incredibly exclusive club, available in less than 1% of the country across small pockets of 19 states.
-AT&T has the largest 100% fiber-optic network in the nation, spanning over 21 states. If you move, change neighborhoods, or want a service you can actually sign up for today, AT&T is vastly more likely to be available at your address.
-If you already use AT&T for your cell phone service—or are willing to switch—choosing AT&T Fiber becomes an absolute no-brainer. Google Fiber does not offer traditional mobile carrier bundling.
-AT&T deeply slashes prices if you pair postpaid wireless lines with their fiber. You can secure their 300 Mbps fiber tier for as low as $35/month when bundled, alongside ongoing bill credits or visa reward cards (often valued up to $200) just for signing up.
-While both providers give you excellent, cutting-edge Wi-Fi equipment for free, AT&T includes a much more robust built-in security layer.
-All AT&T Fiber plans come with AT&T ActiveArmor internet security. It operates at the router level to automatically block malicious websites, prevent phishing attacks, and secure your smart-home IoT devices (like cameras and smart plugs) from being hacked. Google’s app features are much more bare-bones by comparison.
-If you are looking at ultra-premium speeds, AT&T's top-tier offering holds a distinct value edge over Google’s maximum configurations.
-AT&T's 5 Gig tier sits at a highly competitive price point ($120–$125/mo with discounts). Furthermore, AT&T includes their All-Fi Pro program at this level for free, meaning they will supply you with as many mesh Wi-Fi extenders as your home physically requires to eliminate dead zones, alongside premium tech support.
