I switched to Kagi about 6 months back. It is overall better, but at least on par with Google, also as far as tech / programming - related questions go. Whenever I do not get a useful result from Kagi, it literally finds nothing - I then try Google for verification, which also lists absolutely no results. That happened approximately 4 times since I switched.

Kagi is worse than Google for: reviews, memes, porn, as well as “descriptive” searches, i. e. when trying to describe the desired result using natural language, e. g. “video game character that swallows everything” (I made that up just now for Kirby).

Kagi’s ability to use lenses and assign weights to sites can make a big difference.

At first, they didn’t have anonymous payments and an unattractive pricing model, but that has been fixed for a while, otherwise I wouldn’t have switched.

Overall, I am very satisfied and have absolutely zero plans of ever using Google again.
