To address Guinness' core issue here is what I have learned lately.
OLED provides the best picture I have ever seen (Photo Quality)
However they are pretty expensive and nobody knows how long they will last. (No History)
Trailing edge technology (Last year's models) give the best bang for the buck.
Watch out for smart TV models because they may or may not work well with your peripheral devices like Fire Sticks, Play Stations etc.
What ever you buy you will be sure to find something way better and cheaper about a week later.
Good Luck and Happy Shopping
