For me, DuckDuckHack has always returned really awesome results on top of what I consider to be a fairly lackluster set of results for some searches that bing provides. If another provider wanted to step it up with extra sauce on top, I'd be more than happy to try if it makes my day to day better.

Different results from Google and Startpage are expected, because Google offers personalized search adjustment. Even if you're not logged in, Google uses Ubercookies and fingerprinting techniques to identify you as a unique user
