Lot of folks have gone back from OLEDs to Qleds like I and Vikrant n vice versa... it's subjective as QLED and OLEDs both have limitations.And moreover top grade QLEDs are as costly as OLEDs if not more. So they might as well buy OLEDs for that price point. After going OLED, we can't turn back to these huffing and puffing to solve multiple problems related to LCD
OLEDs obviously wins in black department n also viewing angles, while QLED is superior in brightness , has pure whites, more pleasing , richer n vibrant colours , better colour volume.
Why did I go for a new QLED after splurging on CX only 8 months back : I find that QLED apart from its traditional strengths is lately getting quite close to OLED blacks n thus offers a more all-round value for me.
