My experience with the Final Four games was the Duke/MSU game was unwatchable on TBS. Kept getting "Content not Authorized" every 5 minutes. I could reload the channel but it would pop up again. And that's not the first time I have seen that message, other times its just annoying, it happens once after an hour or so and its fine. But TNT was fine. It was the Duke Teamstream which wasn't ideal but I could still watch the game. So my experience wasn't as dramatic as others, the game was still able to be watched. Once the UK game (the one I really wanted to watch anyway ) came on they had fixed the issues and TBS was fine.
Yeah there are hiccups. But also we had some severe storms last Friday. In the middle of the storm while watching TV I turned to my wife and said "Dish would have gone out in this weather and here we are watching live TV". So yeah there are benefits (and yes I understand cable would have not go other either).
