Bing is not using google's algorithm that's why bing managed to survive the panda update. Panda update to new google algorithm made the search quality worst. Still google claims that bing copies their results but i don't see it that way, bing is still relevant whereas google is mobbed by ehow/about.com results. About.com and ehow made pages to generate pageviews with literally 1-5% of useful information and rest is crap.
Try this for example, 'phoenix haiku' in both google and bing. Bing gives you result for exact poetry/haiku related searches. Google gives you map of haiku restaurant and few other vague places on the internet that has nothing to do with meaning of haiku.
