I bought this TV for it's picture. You can add smarts to it for as little as $30 through Chromecast and you can go all the way up into the hundreds through Android and Aple TV. LG does not have a lot of apps but the interface is clean, voice search is good, integration with DIRECTV is good, and even if the Smarts completely stopped working on it the TV would still be top notch. At least mine is.
All of these platforms have their shortcomings. I own just about all of them. There is no one solution a combination of about three will get most people right where they need to be.
