You may want to just try one for a few months, then the other if they don’t seem good enough. I’ve used both CL/Lumen/Quantum DSL and xfinity cable around CO in the past. It can really depend on a home to home basis.

The CenturyLink product tends to “feel” more responsive as it tended to have faster back end services, but overall up/down speeds were slower. If you can’t establish a fast uplink due to distance/wiring, video calls and cloud services will become unusable.

Another option, maybe, would be Comcast Business Internet. They have no caps, higher network priority than consumer, faster support turnaround time, and you do not need to be a business to get it. The trade-off is top speeds tend to be a bit lower for the same price. If they offer Xfinity to a home, business service should also be available.
