I agree it sort of sucks what Plex is doing regarding their change over. It doesn't affect me personally, as I also don't use their DVR or Live TV functionality as it never worked well for me from the beginning and didn't play nice with other Live TV services I used at the time side by side.
While I feel it would be nice to have an "all in one" solution to our Movie/Recorded TV watching I just haven't been able to find it. It seems like every server type software has one thing about one part of it that I dislike.
I have used Plex, Emby and for local playback even Kodi. Both Plex and Emby have their drawbacks in the Live TV/DVR area that I dislike. I could go either way with Plex or Emby as regards my own personal media playback (both local and remote). I usually use Emby mainly because it does some things I like that Plex doesn't do as well for me personally (collections for example). Playback quality, general usability for example are about the same between the two.
However, for Live TV/DVR Channels has been hands down the best. I have had very few problems in the past year of usage. When some little thing happens they fix it pretty quickly and even the little things have just been very little things. Adding in the ability to skip commercials just tops it all off for me.
