I really like the one I have. A relative has a much older model and it still works fine too.
It’s very responsive and the 4k models are quite powerful and future proofed IMO. If you have an iPhone you can quickly use it as a remote too.
Paired with infuse app it even does local streaming from my media server well.
And it’s cheaper to get this year’s top of the line Apple TV than it is the 2019 Nividia shield pro.
M-Discs had merit in the DVD era. It’s a common refrain of those who don’t know the intricacies and read a wired article years ago to claim they mean anything in the Blu-ray era. They don’t.
Standard Blu-ray Discs have all the technologies that supposedly make m-discs so long lasting and as far as media that isn’t continuously updated and hashed from live storage medium to live storage medium (cold, archival storage unpowered) they are about as good as you’ll get.
They are much tougher than DVDs. Of course a variety of things go into how long a disc remains readable and without damage to data including luck with regards to no impurities in the batch. Even m-disc themselves based their longest claims off storage in ideal situations like an inactive salt mine (commonly used for archives by governments). Kept out of sun, away from extreme heat (including baking in uninsulated 120 degree F heat all summer year after year), away from high humidity and away from UV exposure to the data side of the disc as well as scratches and such and they should last a quarter to half a century, some more.
In the Blu-ray era m-discs are just an overly expensive brand.
