I use Bing as my default search engine, but for anything tech related, if I have trouble finding it on Bing, I switch to Google. There is clearly a difference between the two.
Google seems to have simply more pages indexed and that helps with obscure error messages or API usages, but seems to hinder it when searching for anything relatively common.
That's my experience as well. Because of this I use DDG as my main search engine now, mostly for privacy but also because I can switch to Google when it or Bing's index is lacking.
I don't know. I'm not a techie but a math student and most of my searches are math related, not technology related. When I took the Bing challenge Google beat Bing 5-0.
I also had similar results. On the searches where I chose something I knew about to search for, I always chose Google's results. On the one example where I chose a suggested example (Halloween Costumes) I chose Bing. My other searches were for a specific camera, the type of a battery used in an old film camera, a historic sail boat designer and a Rails method.
The two thoughts I had were: 1) Have the suggested examples been prescreened to favor Bing? 2) Do the Bing results favor a shallower explorations of topics while Google's favor more in depth ones?
