My experience with DDG has been the opposite of yours. The results some of the times are just annoying. Mostly because I want it to be good enough to replace Google with it. I click on a second page from results and it turns out to be some dead unattended page.
I gave up trying to be too optimistic about DDG and use Google with no javascript and no cookies saved on the domain in my browser.
My problem with search is a user one. Not an ethical one. When I search for something I want the best results. I don't care if some cute furry animal had to be sacrificed in the production of this utility.
Btw, DDG has a settings button hidden somewhere that allows you to tweak a few settings and save cookies if you wanted.
