Which resolution would you all play pvp games at? 1080p @ 240hz or Ultrawide 3440x1440 @ 144hz ? Those are your only option, which one would you pick? Powered by at i7 9700K rtx 3080 12gb and 32gb ram 3200mhz

I already have both monitors and not looking for a new one atm.  I am using the ultrawide for games like GTA 5 and spiderman and rts games.  But I am also playing Arma 3 and Fortnite on it, and I am wondering if the 1080p 240hz would be the better option for pvp centered games?  Or stick to the uw for everything and use the 1080p as a 60hz youtube monitor?
