It's not that it's better than google (although it is for some types of searches). It's that it's not worse. Bing and DuckDuckGo are worse than google. I tried to switch to DDG many times, but fell back to google at least 1/3 of the time.
I haven't googled a single thing since switching to Kagi. Easily worth the $10/mo to not have my search history monetized, and to work with a company whose incentives are maximally aligned with giving me the content I am searching for.
Kagi also has nice features like personalized upweighting/downweighting of certain websites.
The Kagi team is also super responsive to feedback. I've submitted a few bug/feature requests that have gotten fixed within a week or two.
It's amazing that a small team can compete with google.
