Kagi seems to be the real deal. I’d say anecdotally it cuts my searches in half (If I had to do 4-6 searches to find something previously, now it’s 2-3 max). Sometimes I will find myself accidently on DDG and I’ll think, “Wow, why are these results all over the place?” DDG still edges out Google and Bing (actually I think it uses Bing as a backend for certain tasks).
