OLED or Gsync Pulsar for The Finals

[Tygr]

trying to figure which monitor is better for my needs.
currently im playing with dell 1080p 320hz monitor. it's fast but not clear at all. and enemies blend and hard to detect.

thinking about either OLED. or New gysnc pulsar.

13600k, 4070ti.
mostly playing The Finals (fast shooter) and sometimes singles/arpgs

I'm trying to figure if oled instant respone time and colors worth over gsync pulsar

thanks
