Hi All LG OLED TV owners, I wanted to know which is better for features and functionality, the LG tv's built in Amazon prime video app or a dedicated Amazon Fire stick/Fire TV? I can think of one advantage of using the separate amazon fire stick or the faster fire tv, is that you have a dedicated remote and can use voice control/alexa, but are there any other differences between using the built in TV's app or a separate dongle? picture quality? sound quality? speed in streaming? any differences in the number of menu options? Thanks for your input.
