I do disagree with this, in that #Bing's search results aren't just bad because they can only crawl 90% of the sites that #Google can. Bing's results are bad because their ranking algorithms fail to put the information people are searching for at the top of the results. If one clicks through 9 or 10 pages of results, one might find something relevant, which was probably why #Yahoo and #DDG used to deliver better results than Bing, while sourcing most or all of their results from Bing.
