I've had no issues with my LG OLED. Picture quality is great and the UI doesn't suck.

With the newer LG TV's there is a jellyfin all. Ignore the people that say don't connect it to the internet you probably don't care and would be annoyed you can't use the features anyway. For things that don't have an app through the TV you can also use the browser that's built in.

Be careful buying android tv boxes as they can be super sketchy way more so than name brand TV's.

Roku boxes also seem to have an app for jellyfin that has been pretty reliable.

Edit: one annoying thing that seems comma among TV's is that the ethernet is limited to 100mbps and you'll get faster speeds through wifi.
