LG TV’s are really really good. If you never connect them to the internet. And that rule should be applied to all TV’s. Use an external device like an Apple TV or a self-crafted solution (Roku, Amzn stick, etc all garbage phoning home and listening with Alexa crap)
Treat your TV like a computer monitor (ironic here in this context lol)
Image quality may be good (minus the horrible banding and ABL) but I'd put LG and Samsung in the same bag concerning hardware reliability: don't expect it to last much more than the warranty period and if it does, give some offerings to your lucky star.
In my experience they are both good. I have a 15 year old 1080p Samsung 55” panel that has moved across the country 3 times. It’s in my garage and still works great. My C2 OLED is 5 years old, knock on wood still working great. B5 OLED latest in my fleet it’s only a year old.
