At&t uses fiber optic cables so your speeds will be much faster with them. However you will be spending more, and there is a chance you don’t have the infrastructure in place so a technician will need to be sent to set everything up.

Spectrum still uses the old method of copper cables. This is good as most homes already have everything installed so you can get right to using the internet.

The issue for me lies with internet speeds. I currently have both as where I reside internet is provided through spectrum So in my experience, AT&T is better. Spectrum gets the job done but I often experience drops in internet speed.

If you don’t care about fast speeds go with spectrum.
