I was gearing up for writing a long response but I can't do any better than this.
I can't go back to Google. Can't. The awfulness is so apparent after you've used Kagi for any length of time.
I will say I wish Kagi had a "shopping" mode. It does such a good job with removing ads sometimes when I'm actually looking to buy something it lets me down. But then I gnash my teeth and do a Google search. Google is always up to sell you some shit.
Seems like a "shopping" mode would be a good way to get Kagi some revenue, too. If, like it's AI features, it is completely optional and under the control of the user.
