QLED is the more feasible purchase in terms of monetary value and outcome, where intensified brightness and a longer lifespan are considered. Yet, for someone who lives to pay more for better viewing, be it in cinemas or at home, then OLED is the only preference they need to have. Better viewing angles, deep black levels not requiring a lot of backlight, consumes less electricity, is the banger for gamers, and the light emission is certainly better for your health. The lifespan is pretty good for the price you would pay because OLED 4K TVs will last you for about 6-8 years.
