In my experience, Samsungs have the best picture. The one we got upstairs is old, and the pic still looks great. I don't even remember having to fukk with the settings too much
I've always felt they do out of the LED sets. This last one is my 5th Samsung, only issue I've had is my 65 has some strange vertical color banding, I think might be an update issue. Gotta call Samsung warranty about it.
