I love that Kagi puts the "monetization" icon right next to results so I can avoid navigating to them. This means I'm much less likely to click on Medium.com links and other monetized blogs and sites. Often times the good content is on some personal website where the creator doesn't really care about earning money off it.

Another neat feature is the possibility to rank results or block them manually so you can lower visibility of certain sites. Really help push the scammy sites down.

Compare this to Google Search where the first half page is paid results (ads) and the rest of the results are of dubious quality. And you don't really have much of a way to influence your search results.
