Best 1080p streaming device for Plex

Looks like a timely update for the webOS app (though still in preview):

I have a Roku 4 right now and the battery on the remote totally blows! How long do the batteries in newer Roku devices last?

I forgot to consider about the LAN connection. I’m aiming for everything to direct play so as much as possible a Gigabit connection is preferred over 802.11AC wifi. So the Fire Stick has a separate adapter for this?

How bad is the Fire Stick Plex app?
