News, rewards
I use Bing for two things. First, for Microsoft Rewards which lets me earn points while browsing their news feed each morning. I find their feed less targeted but more current than Google Assistant and less jumbled than the Google News app, When going from the All option to the News option on a general search I find it more useful than Google. (N.B. I don't know if Microsoft Rewards is available outside of the US.)
I also use Bing for those websites I can't avoid that don't work with Firefox (where I spend almost all my browsing time.
