In my experience it's at least marginally better, but one of the really nice features that Kagi has (and probably the main reason I subscribe) is you can extremely easily block domains. So whenever I hit a SEO garbage site, I just go back, block it, and I never worry about it again. In the areas you regularly search, this quickly gets you to a result page that is substantially higher quality than google.
