I use two systems all the time, the TiVo has the Live Guide, the DirecTV has the Grid Guide. I use both with great regularity, and much prefer the TiVo Live Guide. It's easier to use, easier to see more channels and more upcoming shows at a glance. There is nothing better about the Grid Guide. Really, I'm sitting here trying to think if there is one thing I prefer about it, and can't think of a single thing.
