Those of you who did enough research will know that all the LG 2017 OLED models use exactly the same technology.
The W7 and G7 are the best in the lineup but it's only the looks and the speakers that differ from model to model.
I am about to pull the trigger on the E7 OLED but it would be a better choice to go for the much cheaper B7 (since the screen technology is the same) and hook it up to a Dolby Atmos receiver.
