I'm very happy with Kagi. I find the search results to be excellent. It does take a little bit of practice to get back into the habit of writing proper search queries instead of relying on google already having a profile of what you're likely to want, but once you do its very solid. The features to promote or demote domains is also very useful.

Funny thing is that occasionally I'll search for something with Kagi and I'll get no or very few results only to then try google. Google will then show me millions of results but it's all unrelated, AI generated, SEO trash that'll just waste my time. I'll take no results over that any day.
