These meta search engines have existed for a while now but they're damn useful.
I find them a few milliseconds slower but it's tolerable and improving constantly, I'm pretty sure they just use Google for you hence the name meta search engine, or at least the difference between Ixquick and Startpage (although they're owned by the same people and look the same) is that one pulls results from Google only and the others pull from a variety of other search engines like Bing and Yahoo.
Ixquick and Startpage are nice, however I prefer Duckduckgo simply because I like the look and feel better and I have a good settings configuration and dark theme with that site.
If you really want privacy when it comes to your search engine queries, definitely have a look at Duckduckgo and Ixquick/Startpage.
