“Good move” to capture the queen but “Best move” to capture the knight?

Because I’m on the chess.com mobile app I don’t think I am able to send pictures but if anyone knows how please Lmk. I was playing a 10 minute game and captured my opponent’s queen. After I did the game review I saw that it was a good move and capturing the knight with my bishop was the best move? The queen wasn’t trapped and could have gotten away if I didn’t take it. Is this just an error with the game review?

Also it said that bxf6 is best because “I am threatening to win a pawn” ?
