I didn’t realize Bing had a map app, and I’ve never heard of NaviExpert of Yanosik. Granted, sample size of 1 (actually a half dozen or so—my immediate family haven’t heard of these either).

Nobody uses Bing, which is just another combination of TomTom and OSM like old Apple Maps was.

(You can tell nobody used it because it was just as bad as old Apple Maps but nobody complained about it.)

Their only appeal is they sometimes license nicer satellite images than other people.
