I have never used anything but google, duckduckgo and startpage. I always end up coming back to google because the results are not as good.
Well startpage has the same results as google, but i stopped using it for reasons I forgot.
What made you chose Kagi?
Tested it and found it realized doublequotes something none of the big ones that I can access (bing, ddg, google) does.
That was it.
And the first time I saw a reported bug in the search results getting serious attention and a fix I was sold.
Or boost or even pin sites that I feel are extra valuable.
Back in the old days I had a txt-file on my desktop containing domains with a minus in front, llke -example.com -example.org for all the worst offenders, so that I could post them on the end of every contested search.
After a while I think Google found a way to ignore those as well as every other filter I had - at least I gave it up.
