The gap has been favouring bing (DuckDuckGo) for a while now in my experience. Every time I use Google or just doesn’t find what I’m looking for. Just a few days ago, when Bing was down and I had to use Google, I tried searching for the new beta nvidia Linux drivers. Google didn’t even include the official nvidia site in the first page of results. When I later searched for the same thing again, using DuckDuckGo, it was the first result… and stuff like that happens every time I need to use Google. The only category Google still seems to have a slight edge in is current (as in happening right now) events.
Bing is the default engine in Edge which is the default browser on Windows. There’s a huuuge demographic who doesn’t care enough to change either of those.
Also, Bing profits from other search engines using their results as a base. DuckDuckGo, for example, uses Bing as their primary source for search results. And in my experience is better at it than google, these days.
