I prefer the self-hosted searxng. It's customizable as hell. Pretty decent search results.
I know some people trust and use kagi....Even if they're privacy oriented and you pay to use them, making them a little bit less incentivized to sell your information, it's still another company and at this point I have such a deep distrust for any fucking company with my own data that if I can self-host it, I will. That's just me though. I'm sure kagi a decent search company. At least so far they haven't done anything nefarious that I've read about.
