That's surprising to me. I find Kagi's results to be better than Google most of the time. Sometimes they are really exceptional, with searches I thought would be tough taking me straight to the right page. Maybe it depends on what you tend to search for.
There are other benefits to Kagi that I do miss though. I liked being able to permanently disclude domains I am not interested in, and to boost the relative importance of others.
I found myself questioning some of Kagi's search results when I first started using it and sometimes thought a search result was of poor quality, but whenever that happened, I did a direct comparison with Google whose result was equally bad.
I've now used Kagi for almost six months and have never found a search where Google provided better quality results. Except for image search.
I use a strict adblocker, so finding what I'm looking for on the Google search results page is actually quite easy for me. I recommend checking out uBlock Origin[0] if you haven't already.

Edit: You.com is a mildly interesting product, but not what I'm looking for at all. It has more ads than Google, and the default is to send my query to OpenAI and wait for it to spit some text out. No thanks
