Good point!
Im not using it, maybe never will anytime soon. But moving forward I would never buy a TV without it.
I suspect you are not considering Sony because of price but their models are well worth it in the $1200 to 2000 price range. For 65 inch and higher.
Awesome sets, I am talking about the Bravia X series. Of which in an 85 inch model is around $2000
Forget about the Technologies and rely on the quality of components of set you are buying.
Every technology can be unreliable or cheaply made, its more marketing than reality. Price with Sony, Samsung and LG rule for quality. Buy their upper tier sets, they all make lower tier to be competitive with the "off brands" and some of those are made by the same sub=contractors.
You can make sure you are getting an upper tier by going directly to the website of the manufacturer.
A Sony Bravia XR series is a solid choice and one you will never regret. Never
