I switched from 3 years of bad Comcast cable to AT&T 1G fiber recently. They were professional and ran the fiber from the pole to my house in a few hours.
I ran a speedtest on fast.com and got 985Mbps. The service uptime and quality has been utterly stellar. AT&T has been really good to me, but not everyone has access to 1G fiber.
Sounds like you had a choice of service providers where you live. That might explain why the service was so good. Unfortunately, most americans don't have a choice of service providers, or only have one fast provider (eg. cable that goes to 100mbit, but DSL that only goes to 10mbit).
