Google has run a sting operation that it says proves Bing has been watching what people search for on Google, the sites they select from Google's results, then uses that information to "improve" Bing's own search listings. Bing doesn't deny this.
So - If you're using Bing for searches and you think the Bing results are superior to Google's, it's an illusion.
