Wanted to try Neeva since they launched, but DuckDuckGo has served me well over the years and I can't really complain about the results. Only on a rare occasion do I need to make a long-tail query where I surmise Google/Neeva will do a better job at results. That's once every ~1000 DDG searches though, and I append a !g command to my query to redirect to The Google in that case.

I will continue to use Kagi[0], keeping in mind that could be shutdown without notice too, so I'll probably end up using it more now.
