EVERYONE I know that has or had U-Verse has had nothing but issues with it. U-Verse doesn't work worth a darn where I'm at because it goes over copper at some point.
Can't speak to the copper experience. I've had fiber to my home for the past 10 years. Once uVerse was available, it has been great. I can count outages on one hand, and the last was caused by the AT&T techs cutting/breaking fiber working another issue. I was home and noticed them at the pedestal and said "Hey, did you guys knock out my fiber...."
The fixed it in about an hour while there.
