AT&T U-verse or Cable

My wife and I will be moving into our new home at the end of the month and are deciding on whether or not to continue with our current cable service with Time Warner or switch to AT&T's new U-verse.

My complaints with Time Warner are the shitty cable boxes, the $10 per month charge to have digital cable in another room, and the fact that the signal constantly degrades during peak viewing hours. Plus, only about 1/3 of the channels are actually digital. However, I have very few complaints about their internet service. it's fast and rarely goes down.

U-verse on the other hand, has 100% digital quality channels, offers three rooms at no additional cost (all HD with one a DVR), more channels, on demand, more HD channels and a better cable box (developed by Microsoft). However, their fastest internet service is only 6mbps down and 1mbps up compared to cables 10mbps down 1mbps up.

So here's my question, am I going to be lagging during my marathon online game sessions with the slightly slower U-verse DSL or will I not even notice it?

Does anybody have U-verse that can tell me more about the television and DVR service? Some things I've seen say it can only record 1 HD channel and three SD channels or 4 SD channels. Is this true?

Thanks

Update: I read a review article and it does in fact record up to 4 SD streams or 1 HD and 3 SD streams which is a bummer since most of the shows I watch are in HD. However, rarely are they on at the same time. Also, a big bonus that may have me overlooking the 1 HD annoyance is the fact that the other recievers in the house, can pull the content from the DVR.  NICE!!!!  Now my wife can watch her recorded Nouvelas in the bedroom without bothering me.
