My opinion is that you should think of the size, location, and budget first.
Unless you are rolling in dough, many times TVs that are last years best, or the year before, as well as new can be 90% as good as the best, at a fraction of the cost.
Just plan on getting another in 3-5 years.
Look at what you watch, how often and how the room lighting is.
Some screens will do better if watching daytime with sunlight, others will do better with sporting events, 4K content. Are these programs you do watch..? Extended Warranty, if cost effective to total cost.
In house service on the warranty, if the screen is large enough.
Lastly, if it fits you, grab a new CC with a couple hundred dollars cash back on a large purchase, and save even more. I was floored this year and the quality and sizes available under $1000 over the Holidays.
