Benefits to using both Google Analytics and Omniture / SiteCatalyst?

[Jenny1]

Hi - we currently have Omniture implemented on our corporate website. Do you think there is anything to be gained by implementing Google Analytics as well? I'm wondering if any of the data Google is blocking from Omniture is available in GA. Or any other benefits???

If you are using GWT, AdWords or AdSense they can work alongside Analytics to provide more accurate data.
