They're all garbage. Content farms and SEO nonsense has been flooding search engines with useless garbage for years. Either that or pages that simply copy forum threads over and over and over so you get a whole results page of what appears to be different sites, but are all a copy of the same forum thread from 2007. Or they grab your search string and then you have a page that looks like it's exactly what you need, only to find out it's scammy bullshit. But AI is making that whole problem exponentially worse.
I've tried DDG many many times over the years. Sometimes it's ok. But overall, most of the results i get just aren't relevant, and it seems like over the last year or two DDG's results have gotten way worse. I always end up back on Google. As crappy as Google is, the results still end up being more relevant overall.
