It is probably massively better for niche technical searches which many technical people here do for their job, that is the Kagis userbase after all.

But such searches doesn't generate much ad revenue, so it doesn't do much to Google to lose them, all the people searching for articles about makeup or clothes or games or other things that has strong advertisement potential Google is awesome as a search engine, I haven't seen anyone say Kagi is better there. Kagi is only better for the searches that Google doesn't care about since they generate so little ad revue, Google uses so much compute per search that I'm not even sure such technical searches would be profitable for them to run, likely that would increase profits to lose them to Kagi.

That is something that you can only decide for yourself.
