I'll argue that Kagi is the best search engine in the world. If there's any better out there, I'll switch to that. For $10 per month it's a bargain. But "free" does things with people's reasoning. As you admit, you'd choose free over the best food in the world most of the time, even if the best food was dirt cheap. I'd choose the best food in the world over free every time, if it was that cheap.
