I've had bing as a default on mobile for a couple years now. And I have google, bing and ddg as defaults on different browsers (chrome, safari, ff, IIRC). Trying to mix it up decently, and bing for my mobile searches hasn't been bad at all.

FWIW, people still often react weirdly when I tell them to 'bing' something. "When was that movie released?" "I dunno, just bing it". Reactions are usually confusion, mild amusement, but sometimes I've had some weird aggressive/anger issues emerge when I've suggested someone use bing. Strange...
