It’s been a while since I compared, but when I did… Bing was almost always better when I did very specific searches, and Google tended to be better at guessing what I wanted to search. Since then, Google has gotten worse at basically everything so… to your question, probably the opposite.
I don't use bing directly but I use DDG which uses bing and I find most of the time its fine but especially for work/science related queries stuff just won't come up and I'll try it on google and get the useful result near the top.
I've used DuckDuckGo from 2012 until 2022, when I switched to Ecosia. Both search engines uses Bing behind the scenes. In my opinion the results have been "good enough" for a long time and as good as Google for at least five years. In the later years Googles results haven't exactly gotten worse, but the layout of their result pages have been degrading fast. So while Google can still find what you're looking for they are hiding those results in favor of showing more ads and trying to keep you leaving their site.
It is a little surprising what Google still maintain such a high market share, but that's momentum and force of habit for you.
