Dogpile started out as an aggregation of the results from other search engines and may still work that way. It often provides results early in the listing of results that don't show up until far down the list in either Google or Bing because it seems to be very good at removing redundent results.
Bing is FAR superior to Google and seems to have some degree of protection against manipulation although from time to time you will run into something that has obviously been manipulated to force an agenda driven page to appear early in the search listings. Even then, Bing seems pretty good about finding and getting rid of those sorts of things. I have heard that some people have a problem with Bing when they try to go twenty-five and thirty pages of results deep looking for something. I don't recall whether the the later pages won't load or if it's more along the lines of later pages taking a long time to load. Other than that, though, everyone I know who switched to Bing is happy they did.
Google is a propaganda machine disguised as a search engine, at least that's my assessment of them. They make money by shoving ads in your face as if the ads were what everyone has been searching for and obscure the truth by making sure things that agree with their agenda show up early in the results of searches.

What you don't understand is that search is not Google's product. You are Google's product. Google doesn't get paid to index the internet. It gets paid to deliver your attention to advertisers. Being better than its competitors at indexing the internet and organizing the world's information is simply Google's way of inducing you and millions of others to serve as its product.
The same is true of Bing. If you are not seeing ads on Bing, it just means they're incompetent and being kept in business by their being part of the left-leaning Colossus of Redmond (if you use Bing or Windows or Office, you are helping to finance leftard causes — live with it).
If you don't want to be a search company's product, you can sign up for Lexis/Nexis (for big $$).
