Last week my ten year old Samsung died. It would have cost $300 to repair it. Instead I bought the LG 65UK6300PUE (65") smart TV. The TV tuner is outstanding! The best I’ve ever seen. It brought in 40 stations whereas all my other TVs, tuners and DVRs get 28. In my experience this LG tuner is the best period. I love WebOS and the Tablo app is reliable under WebOS 3.5. It also has Netflix and Amazon Prime. Now the only reason I need my Roku is for the Britbox and Acorn apps. The LG was on sale for $804 on Amazon (and since I have Amazon Prime no shipping charges).
BTW I don’t think I can ever go back to a dumb TV. My wife and I have gotten used to the smart TV functionality. The TV guide is very good using the data provided in the OTA channel streams and is useful for switching and reminder\notifications. While surfing the guide, the channel shows in a background window
I’m assuming the LG goes out on the Internet to get supplementary info for the OTA guide since it shows posters and data for a show the OTA program stream does not normally carry. Depending on what data a station sends, the LG guide is a 24 to 48 hour grid. Clicking on an entry shows the artwork and additional info. This is an interesting way to develop a free guide… 
My only regret: this TV can get channels the Tablo cannot and thus can’t be recorded
I also did not get the LG Magic remote that integrates with Amazon Alexa and Google Home which I may do so in the future.
