We're a non-iPhone household and went with the AppleTV when my Nvidia SHIELD died.
Ads were getting put on the SHIELD and I definitely didn't want to buy another one because of that and it has been a while since its had a refresh, so went with an AppleTV instead.
The device itself is fantastic, the UI is so smooth and so much nicer. OTOH, I miss being able to cast to the TV more than I expected. It works decently with the Macbooks though (we're a weird household ... like Macs, hate iPhones).
So ... if ya'll have iPhones or don't care about casting, I'd definitely recommend an AppleTV with Plex (the Dropout, Youtube, Disney+ apps are all good too).
ETA: Apple is also making some pretty awesome TV content as well and IIRC you'll get a couple months free with the purchase ... verify that yourself though in case they've removed it, but Foundation, Severance & See are fantastic shows if you're looking for something to watch.
