Do you have some example searches that you made? I’m not a heavy search user and not a programmer but I’ve still found the experience on par or better for all of my general searching.
I tried with the search I had open which was "cf d1" and I was looking for info on cloudflare d1, Google surfaced it #1 and Kagi it was way at the bottom
Kagi allows personalization, the difference is you as a user control it. If you used kagi for decade (assuming this is what you used Google for) I am sure the results would be fine tuned to your preference too.
