Its a strange question, as a consumer, I enjoy choice of Search Engines and hopefully there will be more than two. I may be minority, but my Bing search results feel much much closer to what I am looking for than Google. It could be my own bias or the simple fact that there is too much SEO gaming targeted to Google compared to Bing.
Fair enough but honestly, I pretty much find this true:
* Google
* DuckDuckGo [ Although with the Ad changes, if I don't have an Ad Blocker enabled, this tends to beat Google. As such, it tends to my default since I use JS blocking. ]
There are actually a number of factors that go into which you might trigger the most, our primary source is Yahoo! but we also pull from Bing and Yandex in certain regions, as well as information from 400 other sources including Wikipedia, and our own crawler. You can read more about the sources here: https://duck.co/help/results/sources
We try and provide the best results for a query in a region/language regardless of the price. The only caveat is that we will only pull from sources that allow us to continue our privacy commitment to users.
The rewards are one. Granted, they're not huge (I also use Bing and find it amounts to about 1 $5 Amazon gift card per month), but if you find the result quality indistinguishable, it's enough. Also, like sremani, I want to drive innovation in the area of search, and while lots of people pay lip service to wanting more competition, putting your money where your mouth is by not using Google is the only real way to do that.
True, I really do like the rewards. But I really think Bing would get rid of them if it would was a good financial decision. And I think it would be a decent decision if Bing was doing better.
I'm sure that Microsoft has a great deal of data telling them that the Rewards program has a positive ROI, especially because a lot of the rewards are sweepstakes which essentially cost them nothing. Also, I have watched other people use Bing and seen four-digit numbers in their rewards count on the top-right. (It's agonizing, like watching someone who doesn't know about tab-completion use the command line.) This tells me that the number of people who use the Rewards is quite small and this contributes to its usefulness.
What is the value proposition that differentiates them from Google?
