I love my Kagi account, and will continue to pay. It is too US-centric, something I've been asked to report in HN comments (I have), and something that continues to be a problem.
But as with all of these things, I'm paying to no longer be the product. That's the value for me, and so "it not working exactly as I expect 100% of the time" is actually a small price worth paying.
Generally speaking, I find the quality of results usually on a par with Google.
