I have the new 2017 oled LG. Our new Samsung was rubbish with problems and was taken back. Replaced it with the LG.. sooo much better.
Picture quality is awesome and I previously had the Samsung UHD topend tv but it was broken, which what I’ve heard they have had lots of problems.
The LG also has the new 4K Apple TV, and watching a full 4K movie is fantastic. Even thinking about changing the bedroom Samsung with an LG, I much prefer the LG webtv guide as well so much faster.
