512GB or 1TB model If you plan to store a lot of videos in it. Even for consumption that’s kind of overkill esp in the advent of fiber and 5G internet.
I’d rather set up a PLEX/Media server with that money and stream any content on my local network than having all that junk (my opinion) in only one device.
512/1TB devices are usually for people who edit large files like 4K videos and RAW photos locally. To each his own though.
I have a Plex Server: desktop+20TB NAS for home, laptop+4TB USB HDD for long vacations.
If you travel overseas, internet speeds are not guaranteed. On a 16-hr trans-Pacific flight? Internet's pretty much guaranteed to be crappy.
I’ll admit that I’ve only watched downloaded amazon video content on my iPad while on flights but the quality seemed ok to me to be honest. They’re just normal 1080p content isn’t it?
On the app, 720p with fairly low bitrates. Not too bad on the medium-sized iPads. Pretty obvious on 12.9. Still very watchable for me.

It's like this:
iTunes: You'd be hard pressed to notice artifacts unless you're examining frames and specifically looking for them.
Amazon: OK for the most part but you're likely to see occasional artifacts while watching normally.
Mind, the only reason I even compared file sizes in the first place is because I noticed artifacts and blurring on Amazon videos.
That said, thank goodness for Movies Anywhere. You'll note I only have movies on MA listed as those are the only ones I have on multiple platforms. Kinda wish all studios were on the program.
