I had a more recent 65" Vizio (2020, I think?) in my living room, which was also a great TV. It was something like $600 (crazy cheap for the size!), great picture, never connected it to the net, always worked like a charm. Was a great panel for my Nvidia Shield.
That TV was broken in an unfortunate incident involving a toddler and a thrown wrench, and was replaced with a similarly priced TCL TV (which was the best rated one in my price range on Rtings at the time).
That TV is nothing less than a hunk of shit - constant sound issues, molasses slow UI, built in Roku stuff is all crap. Picture is decent, but I liked the Vizio better.
I've often considered shelling out the big bucks for a better model TV, but given the industry trends I'm terrified of the thought of spending triple the price of my current TV and still hating it. Happy to pay for good quality, but just extremely skeptical of most offerings in the market these days.
