When I bought my Shield TV's I actually liked Android TV. Very nearly every update since then has just slowly made it worse and worse.
Now it's absolutely disgusting as it shows straight up advertisements (not "recommended shows", like literally ads for car insurance or whatever).
So I guess there's really just not much to choose between regardless. It's spyware + adware regardless of price vs. Apple's lack of local backup support :/
Oh I learned it the hard way when my device failed and I I had to replace it and log in and configure each and every app from the start. Half a day gone.
