I'd say so, it has some features I enjoy, eg. I can tell it I never want to see results from Instagram, Timblr, Rinterest etc. They also have a feature called lenses where you can tell it "I'm searching for Java, and my search results should be about programming (not coffee or the island)". DDG I always felt like its results were rather irrelevant in comparison, but I haven't looked at it in a while. Kagi results are on par with the major engines I'd say.
