Directv HD: HDMI or component for best picture?


Hello all,
I own a true HD tv, and I am in the process of purchasing a Directv H2O high definition receiver and their HD programming.
I need help from actual owners of this receiver.
I cannot decide on which to purchase between component video cables or a HDMI cable to use with this receiver for the best video quality.
Questions:
1. When using this receiver, are the video differences between the component and HDMI outputs on it big, small, or about equal?
2. Which output seems better for viewing high definition broadcasts on Directv, and in what all ways?
3. Which output seems better for viewing Directv standard defintion broadcasts?
4. Are the Directv high definition broadcasts as high a quality as the ones I can currently receive with my outside terrestial antenna?
Thanks so much for your help.
