I don't use either one much so can't really offer an opinion, but why not compare the two side by side for yourself at:
bing-vs-google? You'll get the results of your search from both at the same time.
Thanks Flannel for replying.
I have already sussed out the web, but official and clinical test results have always got a kind of uncomfortable feeling about them.
I particularly wanted experienced users to give their comments. I have found often that the ground-root "shopper" knows far more than the vendors or professional analysts about the product.
Frankly at present my impression is that there is not a lot to choose between them, but having said that, Google is the household name for search engines, just like Hoover is the household name for vacuum cleaners. Plus i am convinced that Google has the edge over Bing.
Google and Hoover have been absorbed into our language over time as the descriptive terms for their respective virtues. If you say "Google it", everybody knows what you mean and do it even if they use Bing or some other search engine. Just like getting the vacuum cleaner out by saying "I'll get the Hoover out", when it is not a Hoover at all.
So by tradition, we use Google, but that does not mean Bing is a worse search engine, just that Google is historically more established as part of the furniture.
