That may be, but it's expensive in my area and their support is legendarily terrible. I had ADSL for 6+ years and it was an absolute shitshow. Near the end, they told me I needed to switch providers because they couldn't fix the problem, which was in the drop cable from the pole to house. I had one tech tell me to have a "tree trimming accident" and just cut the line, as they wouldn't replace it otherwise.

Also, I remember a year or two ago a discussion on reddit and possibly here about customers with HTTPS certificate errors and it was ultimately traced after months to a bad router that was mangling packets. MONTHS.

Most people at AT&T are incompetent and the ones that aren't are hobbled by the ones that are. Just my experience. YMMV.
