I believe duckduckgo uses bing for search results. (See https://help.duckduckgo.com/results/sources/?redir=1). If you compare searches on bing and duckduckgo, they are very similar.

The main advantage of duckduckgo is that they aren't tracking you and the ads they show are just based on the search keywords not based on a digital profile they have compiled like google and facebook.
