I stopped using it years ago because they were going downhill and still collecting your private information. I run my own SearXNG now. It proxies from multiple sources, no ads, no tracking. I really enjoy SearXNG as it's mine.
I'd say site blocking is SearXNG's main selling point. (I switched when it got recommended to me on Lemmy :-).) Blocking just a few annoyances (Amazon, Pinterest, etc) make the search results so much better and relevant.
