Most recreational players have probably underpromoted to a rook at some point to avoid stalemate. I do it online as a matter of course if a rook underpromotion would be immediate checkmate because a rook is all you need so why ask for more.

Bishop is extremely rare but it does happen. For example there was the famous case in the US champs when Fabiano Caruana underpromoted to a bishop[1] vs Ray Robson and Robson immediaely resigned. https://youtu.be/umabaHAGmJQ?si=ETy1cAFw7ydH4MhH
