Speed Comparison
Download Speed
AT&T Fiber is the clear winner for raw speed potential.

Coverage & Availability
Spectrum covers 41 states and is widely available in suburban and urban areas. It uses existing cable TV infrastructure, making it very accessible.
AT&T operates in 21 states, primarily in the South, Midwest, and West. However, AT&T Fiber is not available everywhere AT&T operates. Many areas still rely on legacy AT&T DSL (Internet Air / IPBB), which is significantly slower (max 100 Mbps) than Spectrum.

FAQ
Is Spectrum or AT&T better for gaming?
AT&T Fiber is better for gaming due to lower latency (ping) inherent to fiber optics and symmetric upload speeds, which help if you stream your gameplay.
Do Spectrum or AT&T have data caps?
Neither provider currently enforces data caps on their residential fiber/cable plans. Both offer unlimited data.
Can I get AT&T Fiber in my apartment?
Fiber requires a specific line to be run to your building. Check the AT&T website availability tool. If Fiber isn’t listed, you might only see their 5G Home or DSL options.
Why is my Spectrum upload speed slow?
Spectrum uses coaxial cable technology, which has limited frequency space for upload channels. AT&T Fiber uses light to transmit data, allowing equal capacity both ways.
Verdict
If you have access to AT&T Fiber, take it. The technology is future-proof, the speeds are symmetric, and the pricing is competitive.
If AT&T Fiber is not available, Spectrum is likely your best bet for high-speed broadband, significantly outperforming AT&T’s legacy DSL services.
