Yes, I would definitely recommend the update, only for internal media player alone, and of course YouTube app and Netflix 1080 who has better color than my new 4k 55 inch LG smart TV. Yes, UI aka user interface sometime force closed, but very rare and only when I use multiple app like downloading torrent and watching YouTube. But internal media player has improved great, absolutely any video, 1080 or 4 k hevc 10 bit her will play without stuttering or lag, but only from good HDD USB 3 or over Ethernet gigabit capable of 400 MBs sustained. It work with 100 MBs Ethernet speed, but not with high bitrate 60 ffp hevc h265 4k media. It work with sdcard either, but not 4k high bitrate. Internal storage, good USB 3 HDD or very fast gigabit LAN connection with gigabit router are the only option for high bitrate 4k h265 60 fps or 4k h264 30 fps. So, it's much better than previous firmware for internal media player (no lag), for download speeds, for YouTube app witch will play faster and stream correctly 1440 p videos, and Netflix app witch will do 1080 after few seconds of watching, depends on your router and net speed.
