Samsung flat screen TV’s

Interesting to hear about the long-lived Panny Plasmas.  I'd always heard they were twitchy, and mine failed after about three years.
Replaced it with an entry level 65" Samsung, and the picture was pretty awful compared to the plasma.  Upgraded to 4k, and that Samsung has been trouble free for 6 years.
Samsung washer and dryer trouble free for 2 years.
Plan to stay with Samsung when the TV goes:  anyone with experience with the lower end of the 85" range?

All my 65 inch Sony's have been wonderful. No issues ever.

Planned Obsolescence.

Sorry to hear about your experience with Samsung. I've only had Sony and Panasonic over the years with no issues. Current unit is a last gen top of the line Panasonic plasma bought nearly a decade ago. Has moved with me twice and still looks and functions beautifully. I absolutely love my plasma and will replace (when I have too) with an Sony or LG.

"anyone with experience with the lower end of the 85" range?"

I've been looking around for an 85 or larger.  I've learned a little bit by watching the very good YouTube reviews.
The bottom line is where will you use the TV. Bright room, dark room, windows...  If you need a brighter tv or for gaming etc... then you can choose.  
It seems the reviews are very critical,  much like people here about audio. Nothing wrong with it, they are fans of optimal equipment. I say go look at it and if it looks good to you, then it's good. Doesn't matter if it only has 800 nits instead if 1200 nits etc etc...
Personally, I think the Sony 900H is a very good buy. Roughly $2000 at Costco or anywhere. Doesn't really need calibrating. The colors are great out of the box, 85 inches and it's a Sony.
Good luck
