Need opinion on these QD OLED models

These are the current pricing in my local store (price converted to USD).

MSI MAG 272QP QD OLED X24 HDR400 240hz ($495)
AOC Q27G4ZD QD OLED HDR400 240hz ($540)
Asus ROG XG27AQDMES QD OLED HDR10 240hz ($543)
Gigabyte MO27Q2A QD OLED HDR400 280hz ($543)

Purpose: Gaming/Browsing/Movies

Need insight on which one is better. I'm OK with their price range but couldn't go beyond. I just want other people's opinion, experience, any known issues with these models.

I'm currently using gigabyte M27Q 170hz and while I do not have issues with it, I think my overall visual experience will improve when going to OLED.
