I have Vizio M and P series TVs in my house. The picture quality of Sony is the best because of their excellent video processor. Samsung is close followed by LG and Vizio. I worked in that field for many years BTW. The mid range Sony and Samsung or barely average. On a scale of 1 to 10 in picture quality, OLED is probably a 10 but it has a screen burn issue. Among QLEDs Sony is probably a 9 followed by Samsung 8+, LG and Vizio 7+ if you compare equivalent models but Vizio is best bang for the buck and I have 2 x 65, 1 x 55, 2 X 48 Vizio. One in each of the 4 bedrooms, 1 in the family room and 1 in the back Patio. I have 2 x 7.1 Onkyo/Polk systems but in the smaller rooms I am getting Vizio M series 5.1 sound bars.
