Bing's results are now in some ways superior to google's.
I think they are now better for short phrases/key terms. For longer phrases I think Google still has it.
However, sooner or later, some radically different approach (Watson?) might make current search engine methods obsolete. Having said that, there are signs that some of Google's current efforts might involve AI, and they are not promising.
