I don't have any experience with the Nvidia Shield, but looked into it a while back. It seems to be almost on par with the ATV4K.maybe Nvidia Shield comes close but it costs the same as ATV
IIRC, the Nvidia Shield isn't quite as powerful as the ATV4K, but there are things you can do with it that you cannot do with the ATV4K, such as use it as a Plex server.
I would say that it is the ATV's closest competitor when it comes to power and ability.
This is definitely true.Whether or not that’s worth the $100+ premium is up to the individual consumer
Even at three years old, the ATV4K is the best streaming box, but just because it is the best, doesn't mean it is worth the extra cost if all one wants is a simple Netflix and Disney+ streaming box.
