I have Comcast and a monitoring service that sends me a report every month of my streams and more data than I really need and my download speed has been conisistently 18Mbps and the upstream 3Mbps. Latency has been consistent and relatively low and packet loss minimal. So, not a fan of Comcast for TV but their internet has been very reliable and consistent.
I had a subscription to MLB.TV last year and was streaming HD for over 3 hrs every day and often an extra 3 in addition to Hulu and streaming from a couple of network sites and never came close to Comcast's limit (at least according to that chart they show on your account online).

I have a friend in C.S. with Comcast internet who says it peaks at 20 Mbps during the day, but draws down considerably during the evening.
