I work at a big box electronics store mentioned in another comment as a side job (pretty much just for the discount), and I perform a functionality check and quality control check on the TVs that get returned or come back from our service center. I just wanted to comment saying that, in my experience, I prefer the OS and remote on the LGs over the Samsungs and Sonys. However, I personally wouldn't get a 4K TV smaller than 50".
