I've been using a searxng instance on fbxl that points to most engines other than Google and Bing as my default search engine everywhere -- on mobile on desktop, at home and at work. I keep on thinking that I'm missing something, but then if I have a search that isn't coming up with very good results and I go to Google and try the same search it usually ends up with much worse results. I really expected to miss Google a lot more than I do.
