the tube has only 2 gig of ram, while the pro has 3 gig.
2 gig does not leave much for android + plex + buffer for trying to stream high bit rate 4k content. While I’m sure plex (and nvidia) will continue to try to optimize as best possible, no one can change the fact that 2 < 3.
I have both a 2017 pro/500gig and a 2019 tube.
the tube is great for anything that does involve 4k bluray remuxes (ie your makemkv rips).
I use the older 2017 pro when I want to watch any of those.
I don’t have DV, nor do I really care about it, DV is a whole other mess.
this thread @ Plex, 4k, transcoding, and you has info and links to other relevant 4k topics.
Read the whole thread if you want a variety of info and opinions.
edit:
as far as shield as a server, that is something different than shield as a player.
the shield is essentially a phone/tablet cpu + a powerful gpu.
if your use case is a smaller library with 1-3 users, and an external usb drive, the shield may work perfectly fine for your use case.
however the shield will always be limited by the low powered cpu and limited ram and limited onboard storage.
you can move plex/plexdata to an external drive, but that still doesn’t help the cpu/ram limits.
