Developer Starbreeze has promised to make things right (and maybe even start working on an offline mode). Payday 3 could've held this spot, but it's currently mired in matchmaking issues due to its always-online requirement, and a community that isn't happy with how grindy it can be to unlock anything fun. Missions are quick to complete too, so it's a great choice if you need to squeeze your gaming time into a short window.
Payday 2 fans love it for the thrill of completing its randomized objectives without tripping alarms and its utterly chaotic story that involves the President of the United States and John Wick. It launched 10 years ago in a rough state and gradually became the ultimate destination for a particulary brand of co-op fun: heist movie-style crimes with up to three friends. You'd be surprised to learn that, despite having a brand new sequel, Payday 2 continues to be one of the most popular co-op shooters on Steam.
