The facial expressions, body language, and voice acting in Overwatch is better than any other multiplayer shooter

There's other reasons I come back to the game, but the main one is the character development and how it's implemented. In the lobbies of other games I've played recently the characters have voice lines, or do certain things but it's nowhere near as good as Overwatch. Just watching a character's idle animation with their facial expressions and body language gives them so much personality. Regular blinking, eyes actively looking around, fidgeting and voice lines, even yes and no, are done so well and look so good and is what makes me love these characters so much
