Out of the two, I would say Google provides the better range of accurate results. Bing is good too, but I tend to only use it on my tablet, as the Bing search is better for touch screens. However, with increasing data collection and the recent US spying dramas, I feel better using Ixquick on most of my devices. It uses the power of the major search engines, without recording your information and habits. I don't have anything to hide, I'm just against profiling and the monitoring of everything we do (at least in the UK/US).
