I have Netflix, Amazon Prime, Hotstar, Sony Liv, Zee5 (and may have some more) subscribed; using with NVIDIA shield TV connected to my Samsung 4K TV and Fire stick with my Sony TV. One thing I can say for sure is: NVIDIA Shield is way snappier (read faster) when comes to loading of content - both devices are on gigabit Ethernet - so I prefer NVIDIA shield by far. Alas, that TV is on "kabza" from my son, hence almost 90% of time I am operating with Fire TV Stick, again not bad at all...but the lag is very much noticeable.
