It's like Google back in 2010. You find stuff you are looking for without pages and pages of ads, spam, and clickbait.
If you hit a domain which is obviously spam, you can block it forever. If you find a domain you really like, you can promote it for future results.
It's clear that Google's motivation is no longer to offer good results. It's to maximise the time you're on the site, and the number of ads and spam sites you click. Their goal is now, literally, to feed you bad results.
Apparently Google is paying Apple upwards of $20B per year now for search default, so it’s not hard to see why they’re sticking with Google. It does highlight one of many potential anti-trust violations.
