For all the people saying X search engine is better, here's a tool to compare Google and Bing (and Yahoo) results without bias. It simply shows you three columns of results, you click on the one with the best results, and it reveals which ones came from which search engines.
Hmmm, it's giving me the wrong results... it shows the results I voted from are from "Bing", but when I went to Google it showed me those results, and Bing's results where the ones marked "Yahoo".
I've seen this site before and frankly I think it's rather irrelevant. Recent innovations (past years) in search are mostly spelling corrections/related topics suggestions, visual presentation of aggregated results (how many images, results from suggestions) and stuff like that. The pure ranking order delivered on a fixed search is more and more useless, the imo important part is how the search engine guides you until you've found the correct search query that delivers what you're actually looking for.
