My favorite trait in a player is the ability to adapt what they are doing to the players around them. Of course, you can't do this unless listening is more important than playing.

We all know great players, who tend to do the same thing, no matter who they are playing with, or what they are playing... They may play well, but not with others.

Sometimes you have to subjugate your ability, and choose a style and sound that perhaps is less than you would like, but in the surroundings of lesser players, or a simpler music, much more appropriate.

Put a bebop jazz pianist in a country band, and you'll quickly find out if he is a listener, or just a player....

Denying yourself for the good of the tune, or the band is the essence of taste and musicianship, IMO.
