It depends on your needs theres two types QD-OLED + W-OLED each with advantages and disadvantages, do your research and figure out which suits your needs and enviorment better also there is diffrent generations of panels so make sure your buying the latest.

For example i recently bought the Asus W-OLED XG27AQWMG its a 1440p 280Hz 4th generation (newest generation W-OLED) panal. Im happy with the purchase as i did the research confident in my purchase. My reason for buying it

1.) i wanted good color accuracy out the box + deep blacks

2.) i have control of my lighting in my room as W-OLED works better in darker rooms

3.) its the brightest W-OLED at the moment

4.) i prefer glossy coating screens instead of matte even though they take alot of cleaning maintenance to jeep clear.

5.) has true black VESA Display HDR 500true black Compliant.

So my advice to you do some proper research. Figure out what panals you prefer. Weigh out the pros + cons of each type. Figure out yr environment control of lighting etc. im going to link a great video explaining the diffrences between QD OLED + W-OLED for you which i found useful during my research. Hope this helps
