Kagi seems cool, but I haven't felt that google search is so bad that I'd pay ~120/year for search. I think Google's also heard the discontent around search results lately and has been trying to improve - eg. I get relevant Reddit results now without needing to specify that into my query. I personally haven't found cases where the results are so bad I would rather start paying, but would be interested to hear specific examples to open my eyes if people have them.
