I'm using Kagi. I find that it does a better job at finding "legitimate" sites rather than blogspam and content marketing. However I'm not sure I will stick with it a long time. I seems like it has mostly stalled and the team is getting distracted by making a browser, non-relevant AI (I have no problem with the few AI experiments tied to searching) and other side projects. We'll see. I really hope that they pull themselves together and focus or it might not last. But for now they seem like one of the better options available.

Bing's new "Deep Search" where it has some sort of LLM refinement iteration process has also been helpful sometimes. Probably the best AI search product I have seen, but definitely doesn't replace most searches for me.
