Best 240hz monitor for Warzone

[OpticBlast]

First time posting and wanna say hi to everyone. I just purchased a new gaming desktop for competitive gaming. I only plan on playing warzone and the next battlefield when it comes out. I'm currently using a 1440p 165hz dell s2721. I get anywhere from 120 to 170 fps on warzone. I've never tried 240hz before and see that most competitive players are getting about the same fps as me but all use 240hz monitors. Which would you guys recommend to me?
