"Omnibar" is how Chrome calls it. "Awesome bar" is the name Firefox had given its own, even before then. The main difference is that the Omnibar logs all your keystrokes to Google's servers. The Awesome bar searches through the data it already has locally (bookmarks, history, open tabs), and it makes a Google search if the data you entered isn't a URL. Not logging your keystrokes is a privacy feature. On the other hand, the dedicated search field does, and that's its feature. I personally can't see the difference in usage between the Omnibar and the Awesome bar, apart from the fact that the search suggestions make more sense in the Awesome bar, since it only uses my past searches. Follow my advice: use the brand new interface customization UX and remove the dedicated search field.
