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.
