Which Oled 500hz/540hz 1440p 27'' display to buy I can use W-oled or Qd-oled

So I am trying to decide which Oled 27'' 1440p 500hz display to buy I see we have alot of options ranging from gigabyte to asus to msi and I just want some feedback on which ones would you all recommend? Ideally I would want something between $500-$800 max as I feel the asus at over $1000 for a 1440p oled is not worth it.

This will be used mostly for fast paced multiplayer gaming. As I am already set for high resolution oled and va mini led gaming

and how do you think these 500hz oleds stack up compared to gsync pulsar for gaming ? I could also consider pulsar
