LG vs. Sony 65” OLED

I have both brands.  If you have a "light-challenged" room I would tend to favor LG over Sony.  If not, picture quality will be so close I would choose based on aesthetics and price.  Current models have so many adjustment options there is extreme overlap between major name brands.   I also believe both brands readily mirror images if that's important to you. 

We bought a Sony 77 OLED from Best Buy last year. In store we compared LG and Sony OLEDs (we had a LG OLED 65 before) running the same programs, and we liked Sony a little better. Of course, I had no idea what kind of adjustments they have made.

The guy asked us what type of programs we watched more. I told them streaming Netflix, Amazon, Apple TV, and Disney+. He recommended Sony. Again, I did not know if Sony was indeed better. He also said watching cable TV there was no difference between the two brands. 

I was a die-hard Sony guy for years then I realized I've never had one that lasted more than 5 years. After reading numerous positive professional reviews I decided it was time to try the new "budget" brands. We moved to a new house 2 1/2 yrs ago and needed several new tvs. I treated myself to a LG C4 OLED for the bedroom and then three of the Hisense U8's in 55",65" and 100". This was Hisense's top of the line model at the time and they are mini-leds. The OLED was literally almost double the price of the U8's and to be sure, it's an excellent tv. But honestly, the U8's are the ones that frequently catch me thinking "wow, that looks fantastic". The 100" obviously loses a bit of image quality from the smaller ones but everyone that sees it is still pretty blown away by how good a screen that big can look. The LG has come down in price since then, in fact the C5 is less than I paid for the C4. The Hisense has actually gone up $100 for the 65" size. Not sure if that's reflective of a new confidence of the brand in the market or what. So the price difference is not as great as it was and if you've got to have an OLED then I get it. But if I had to buy another tv now I promise you it would be another Hisense U8, or possibly their new UR9, which costs more than any of the mid-grade OLEDS. 

As an aside, Sony just handed over all of their TV production to TCL. They formed a new company that TCL owns 51% of. Sony will still develop their own processing, etc. I have never seen a TCL that impressed me much but I haven't looked in a few years. They may have some higher-end models that are quite impressive like Hisense does. 

I bought the smaller Sony Bravia OLED tv a year ago. It uses the screen as a piston speaker and it sounds remarkably decent. Thats what drove me to purchase it 

I own the 65" Sony OLED Bravia 8. Less than 1 year old.

Just FYI. For some unknown reason, Sony limits its ethernet port speed to 100 Mbps. The WiFi 6 antenna is capable of much higher Mbps than that. So unless you have interference issues, you are much better off using the WiFi 6 antenna rather than the hardwired ethernet port. Sony Picture Core movies require the WiFi connection for full resolution streaming.

Also, as some have already mentioned. I would invest in an AppleTV4K box. If you use the AppleTV app on the Bravia. It is limited to 25 Mbps. However all of the AppleTV original programming stream at much higher bit rates. The AppleTV4K box is capable of streaming up to 40 Mbps. Any AppleTV original or any movie rented/purchased through AppleTV will automatically be streamed at the higher bit rate when streamed using an AppleTV4K box.

One warning about setup. The AppleTV4K processor does all of the audio decoding inside the box and outputs LPCM audio. So your home theater amp or TV must be set to accept LPCM as opposed to bitstream input. The AppleTV4K box makes a substantial difference in quality. Especially immersive audio formats.

Just some information that you might want to consider. I hope that it helps.
