Our verdict
Fiber wins on every technical metric.
If fiber is available at your address, choose it. It delivers symmetrical speeds, lower latency, and steadier performance. Cable is the right pick when fiber isn't yet built out in your neighborhood.
FAQ
Fiber Internet vs Cable Internet, answered
Is fiber really worth it over cable?
Yes — fiber delivers symmetrical speeds (uploads match downloads), lower latency, and doesn't slow during peak hours. The difference is most noticeable for video calls, cloud backups, gaming, and 4K streaming.
How do I know if fiber is available at my address?
