If you could give me either one of those technologies now, with a flawless monitor for a cheap price, sure I'd buy it. ATM Samsung's VA is the closest but their monitors have tons of issues and MicroLED is minimum years away. I have 2017 65" LG OLED now that I game on fairly regularly and I don't have burn in. Presumably image retention has gotten better since 2017, so I'd assume a 2021 screen would have far less issues. If I can get an OLED at a reasonable size that lasts me 3 years of gaming before it burns in that would be fine for me. I'd spend up to $1500 on that.
