The choice between cable modems or DSL modems varies depending on service availability, modem speed, and the user’s home internet subscription plan. DSL service used to have wider coverage, as it’s available anywhere with telephone service. Meanwhile, cable services do not usually reach rural areas, and as such, even the best cable modem wouldn't be suitable. In terms of speed, both services typically offer 30 Mbps speeds, but this depends on the subscription plan you signed up for.
