I’ve got three mid and hi-end three smart tvs and two non-enabled. Sorry, but the smart options ( even on the 2015 Samsung) stink. I greatly prefer Roku— much much faster (even the stick) and have them on all sets. I also have Apple TV on two (never buy a tv that doesn’t have a bunch of hdmi inputs!) which I also like but use primarily so my wife and kids can very easily AirPlay their iPhones and iPads. I am an Amazon prime customer and was sent a Fire Stick when they came out but havent even unpacked it so I can’t speak to it.
