If your searches are this descriptive then yes, I'd expect useless results everywhere. I use Kagi where Bing used to be, for technical reference lookups. It's excellent at putting API docs front-and-center, which means I can alt-tab back to my text editor that much faster. What I love about Kagi is how little of my time and attention the tool requires.
Also my own anecdata - the privacy concerns are a red herring, because the utility of knowing everything you've typed into your PC is diminished when ad surface area no longer exists. I like that Kagi has a privacy focus, but them losing it would not cause me to stop paying for the service as long as the quality was the same or better.
