I've had no problems with LG webOS. Media playback off usb and DLNA is flawless and supports every codec and container I've thrown at it, all the apps work well. I've had it playing 100mbit/sec H265 off network for example with no issues. It's actually pretty hard to find a media player that supports Dolby Vision for example. No Android media box does, and as far as I know Windows support is very patchy. At least with webOS it supports all the video formats the TV supports.
