Most SEOs I'm sure are focused only on Google and skip past Bing. Those in other countries may use the Yandex interface, but pretty much everyone bows down to Google.
We check the Bing profile about every 2 weeks or so to make sure things are indexed etc. Bing provides solid info with their impressions and usually provides a more eclectic mix of keywords in the Search Performance - but these are only words people use on Bing. Still, I often find phrases on Bing that I don't see in the GSC that I then add to websites.
