The extra $20 seems worth it! I’ve never had any storage issues in my Apple TV, but the added Ethernet port and the features it includes (Thread router and anything related to HomeKit Secure Video?) compared to the WiFi version are a no-brainer.
Regarding the refurbished options… I’m usually not a big fan of them for battery-based devices but for this one it could be an interesting option, IMO. Especially if you plan on hiding the device in a drawer or behind the TV (in case it presents any scratches).
I still have the previous version and you made me think about a way to upgrade myself. Thank you (although my wallet does not agree 😅)
I’ve only used YouTube, Netflix, and Amazon Video. All three work great.
I’ve had bad experiences with other services like DAZN because their implementation of HLS is faulty. But, IMO, that’s not AppleTV to blame (other than not supporting, the competitor standard MPEG-DASH): when their HLS transcoding is misbehaving, it just doesn’t work on any Apple product (iPad/iPhone DAZN apps, DAZN’s website on Safari, etc.). Those days, I end up airplaying the content from my MacBook, watching it on Chrome. But again, that’s a technical issue on DAZN’s end.
TLDR, if the services you’re interested in work on your Apple device, they should be fine on Apple TV. And I still haven’t found any streaming service without an app in Apple TV.
