Display Recommendation for 3090?

[AP2]

I currently have a Dell S2716DG (Gsync 1440p @144) and just literally purchased the new Alienware 27" AW2721D (Gsync ultimate 1440p 240) and was thinking maybe I should've bought a 4k monitor instead. Would you guys recommend for a 3090 - 1440p or move up to 4K?
I'm currently playing only 1 game and that is Warzone.

Specs
3950x
16gb ddr4 cl14 3600
RTX3090

Thanks in advance
