I like my stuff minimal on the bloat and advertising, and most TV OSes are the exact opposite of that. Between all the different services and applications LG offers and promotes, it's just not ideal for quickly getting into what you want to watch.
We bought a TV earlier this year for my lady's mother, and got her a Sony specifically for that reason. As much as we wanted a Sony OLED, it just wouldn't work for us. Only two HDMI 2.1 ports, with one being the eARC port, and having shaky VRR support is some wild shyt at that price point. But that's really more a problem with the SoC that Mediatek is giving them than a willful choice. We want another TV to replace an older one in another room, so I'm hoping they figure something out for next year's models, or I'll just get another LG, probably.
