I like both Google and Bing from microsoft too. It has some great features that google doesn't have. just check image search and you will see.. thats only one. Bing introduce themselves as decision engine which help people make decisions other than lot of search results from a typical search engine.
Anyway google still seems to be doing pretty good in search results i saw some tests done by some university but bing from microsoft is close too. So who knows in the future.
