Here in the Seattle area, we can watch both shows since one is at 7pm and the other at 730. Many days I've watched both and notice how far more informative and sensitive the Acccess Hollywood anchors and reporters carry out their assignments. ET does enjoying sucking up to just about everyone.
AH usually far fresher.
Also, it was a bit of an overkill the way ET sucked up to Anna Nicole and Howard. AH was sure on the side of the angels in that important competition.
