As far as I can tell, there are four major search providers: Google, Bing, Baidu, & Yandex. Qwant seems to do some amount of their own indexing, falling back to Bing for other things ( https://betterweb.qwant.com/web-indexation-where-does-qwants... ). Most of the 'alternative' search engines (DDG &c.) seem to rely on Bing and a few (like StartPage) on Google, and I continue to find regular Bing-based search results worse than Google-based search results. Searx is interesting (and what I largely use), and can aggregate from various providers, but it's hard to find reliable working Searx instances.
Search engines like Google and Bing are like a new pair of shoes, imho. You've got to give them a week or rwo of use before they really fit your use case. I used to use Searx, and DDG, and kept having to fall back on Google regularly.
I went to Bing, and had a similar issue. But after its personalization kicked in, I haven't had to go back to Google more than once or twice a month, and in general, I'm happier with my results when I compare the two.
YMMV, though. I trust Google less than I trust Microsoft for search, because the company and its employees seem to lack a "save the world" pathology which I keep getting hints of whenever someone pulls back the curtain on the company's culture. I can intuitively understand a corporate Megalith like MS's interest a lot more easily, so I'm more comfortable deciding whether or not I'm getting a good response from Bing.
But as a daily driver, unless you're really concerned about Google, I don't think there's any material advantage to making the switch.
