It’s unambiguously worse, in part because they backed away from spam filtering after merging with Double Click when the SEO parasites started buying tons of AdWords. There were multiple years where they’d rank the sites which scraped Stack Overflow, GitHub, Wikipedia, etc. higher than the sources, which is not a problem on Kagi in general but also one Kagi doesn’t refuse to give you tools to solve: a Kagi user can block low-quality domains and never see them again. Google not only doesn’t offer the option but if you ever click on a spam site they’ll treat that as a sign that you want more.
