Not trying to be snarky—or maybe just a little—but I own an AppleTV, it’s fantastic albeit very closed. I can’t parse your statement in part because I haven’t googled those things yet (I will) but also because many years of experience have led me to disregard statements like this.
Then you are doing yourself a disservice. Smarttube alone makes me stay on my Nvidia Shield over my AppleTV. It would have taken you a minute to google and you would have saved yourself some embarrassment. Doubling down on ignorance is a wild move.
I did look it up. It’s a 1-person project with many caveats about installation and functionality. It looks impressive for what is, but not an alternative to AppleTV, certainly not if I expect anyone else in my house to use it. I’d put Kodi as a lot closer.
SmartTube is a YouTube app replacement, not an AppleTV replacement. It has a far superior interface and functionality than the default YouTube app. This is relevant to this conversation because you cannot install an app like this in an AppleTV.
I just installed Yattee on my iPhone and my what a horrible app. I then pasted a a valid YouTube link and got the error message that it "Failed loading video". If Yattee is the best you have on iOS then I truly feel sorry for people that have to endure with a subpar app and an even more subpar experience. SmartTube with Sponsorblock is the only way to watch YouTube.
