First time I ever used one was 2004 following the grateful dead on an east coast tour.
One nice benifit was we’d come into town from the opposite direction of the caravan, avoiding a ton of traffic and finding the back route to the venue. Almost always got us better parking and way shorter lines into the lot.
My advice is never use a smart tv of any kind.
Use a third party device like an apple tv or roku, hell even a bluray player with apps on it.
Then get what ever TV you like and never let it see the internet.
I personally like Visio, but any mid grade display is fine.
