I am another that is happy to use just one device. For me my ATV 4 is ok, I mean I like it but nothing outstanding as far as picture quality or sound from any streaming service. I blame my tv for that tho, a 2016 Sony 1080p. And as far as sound, I will use my Pioneer AV to get me Dolby Surround (not a perfectionist obviously) and that satisfies me. One anal issue that I have with Smart Tv’s. I had one in 2015, had my home WiFi setup on it and lightning struck our house and disabled it (blew out all ports on it). So I could not disable my wifi settings on it. It went to the dump and I was worried that some guru, and a cyber theif, would be able to view my wifi settings ( anal, remember). So now having the Amazon App on my ATV (my only reason for using my smart tv (replaced one) was Amazon video), I have turned off wifi and reset tv to factory defaults.
