I use a variety of search engines to be honest. Most of the time without thinking about it I use Google. I do like the results from BING quiet a bit more to be honest. My favorite Search engine is actually DuckDuckGo which uses many different engines in its search. It allows you to remain mostly anonymous as well. You should try it.. it is pretty no frills compared to say Bing.
