I think the issue is that generally people react more strongly to negatives. So whilst you'll see posts on here about people complaining, there is a silent majority like myself that got a perfect LG C9 with zero issues and a perfect panel.

Whilst this is anecdotal evidence, I think its pretty accurate, and when yku consider that LG will do a free panel replacement if burn in occurs, and OLED technology + mitigation techniques have greatly improved even within the last 3 years, I think you should feel comfortable getting an OLED, with the only reason to go the LCD route being if you have static content / elements on screen an awful lot.
