Fire stick has too many ads and hostile decisions, you can’t even turn it off
A decade ago I had a jailbroken apple TV 2 and it was great with what now is called infuse, it took videos directly via SMB and showed them with a really slick interface.
So between the two… I’d buy an Androidtv (real, not a fake Chinese one, like that "Chromecast with Google TV)
If it wasn’t so expensive I’d buy an apple TV again just for infuse. A decade ago was more reasonably priced compared to the competition, right now…
