Both will generally display different results but I think Bing actually goes through and filters things a little better then Google's where they just put whoever pays the most at the top even though it really isn't relevant to your search.
I did read on Digg some while back that Bing actually offers more porn then Google does which I thought was hilarious.
I'm actually starting to get tired of Google as a company in general with their whole idea of saving peoples information, the Google street van documenting people's home wireless information, and just the whole idea that they just want to do it all.
If SKYNet is to actually go live I have no doubt that it will be Google dooming all of mankind.
