I have plasma 65 and 60 inch for movie and game room - for one reason - it does not use back lighting, and can present a perfect black. OLED is by far the best way to go over LED/QLED 4K TVs. The only blocker is price. If that isn't a big issue then get the OLED (LG or Sony). They are the best TVs on the market right now and it isn't even close.

When I spend money on my next TV it is OLED or nothing. I don't care how cheap the QLEDs are.
