Before you buy anything:
How much is your budget anyway?
If you are on really tight budget, can you find TCL or Vizio TVs?
If you can go higher I would look at (adjust to your budget):
Sony XF850 and XF900. <---Android
Samsung MU8000, Q7FN, Q8FN, Q9FN <---Tyzen
Panasonic FXW784 or any of the OLEDs <--- some rebranded FirefoxOS
LG B7D <---WebOS (LG is something special, the OLEDs from LG is more reasonable in price, for LG I prefer to go directly for the OLEDs)
