Sony has the latest NTSC over the air tuner if you choose to use an over the air antenna.
I came to this thread to say the same thing. I have the Sony 77" OLED and the tuner pulls in stations via antenna without turning on my Motorola 50db antenna amplifier. The installer had said as much before it was installed and my other older TV (2011 Panasonic) requires the amp to be turned on while the Sony does not. It really is a superb tuner, compared to all others out there. Not that is is the most important aspect.
I had a 65" LG before he 77" Sony but the previous LG was not OLED, so the picture comparison would not be fair.
Ala sound treatments, the decision on what will perform better should be what is the best TV for that room. If you have windows and a lot of light, go for the LG. If the TV is going in a basement or theater room go with the Sony.
The only other caveat is that if you have Verizon fiber, the Sony TV will likely scale up better to provide a better finished product if you plan on 4K viewing or have a provider whose signal is highly remarkable. I have done a fair amount of viewing using 4K with the Sony and it is fantastic.
My belief is that the darker picture (more contrast) bodes well when a brighter picture - which is what you get with 4K - is introduced. Hence, although I have not seen the LG, if you take a picture that is already bright by nature, and add more brightness via 4K, some details are gonna get lost in the glow.
