That's totally fair, though I personally don't share your experience. It could be that we just use search for slightly different reasons.
One of the reasons I love Kagi is that it respects double-quotes for exact matches. This might seem trivial except I remember being frustrated with both Google and DDG years ago for throwing irrelevant results at me even when I'm querying for an exact match. When Kagi was in beta and I got invited as an early adopter, my feedback to them was that I want a search engine that won't throw crap at me when I'm looking for an exact string match. They've honored that feedback! Even though Kagi doesn't necessarily have the most results, I want double-quotes and things like intitle to actually work as expected.
Another awesome thing about Kagi is how it lets you prioritize certain domain names. Likewise, it's great for blocking domains completely. All of this has made my search results very clean.
To each their own. I'm not saying you're wrong, but to me there's no comparison between Kagi's results and every alternative I've tried.
Oh, another thing I like about Kagi is that it's less censored than Google, Bing, and DDG these days. I used to be a fan of DDG until I noticed that results were sparse or nonexistent for anything even remotely controversial I queried. It became too PG-rated.
