Big fan of kagi.com. rock-solid privacy policy (seriously, I am one of those guys who read them all, this is probably the best I have seen), excellent search results and very nice features (lensed to search in specific contexts only - say, programming, up/down ranking of sites as you prefer, automatic rewriting of urls, custom bangs). The cons, is that it’s a paid service. I am personally a customer since November 2022, never looked back.
