I had tried this a while back, and found it depends on what you're searching.

For technical topics, I had found bing had a preference towards the articles from the microsoft developer network. It also had a bias towards MS technologies.

For example, looking for something vague like real time web server, bing gave a couple results from asp.net pages on the front page, while google seemed more balanced. Google had one link to NodeJS while bing had none.

You could experiment this yourself. I sometimes keep different tabs with different search engines and pick what I like best.
