Supposedly there’s a paid one that is good. I haven’t tried. The thing is Google is completely enshittified. They don’t have to care about you or the sites you search. So my theory is Bing is better because they are hungrier and anything that takes away market share from Google is good—but I’m fully aware that Microsoft was just as shitty as Google and will be again if they get back on top.
Everything else I know of is either just an alternate front end for one of them or an aggregator of both. So you’re right, there’s precious little alternative to Google. But it’s almost bad enough I’m ready for the return of web rings of good sites vouching for each other.
