I have U-verse and, for the most part, I like it. The one downside is that U-verse compresses the digital picture more than most cable providers. Most of the time it doesn't make much difference, but every so often you'll see some artifacts or noticeable pixels in the picture. I see it most often when there's a gradient image (like if they were showing a sunset, or something like that) or when there are a whole bunch of small, detailed images on the screen at the same time (if I'm close to the screen I almost always spot artifacts or blurring on players' caps during baseball games). For most people, and for most of the time, it's no big deal. But for some serious cinema-philes, it's deal-breaker.
About a year ago it annoyed me enough that I had a tech come out and take a look. He told me the U-verse picture is almost always better when using HD component cables instead of an HDMI connection. That's not how things are supposed to work, but he was right: after I switched cables the problem improved.
