I got the 32GB but then Target was running a Black Friday sale of I believe it was 112 for 32GB and 160 for 64GB and I picked up a 64 and moved the 32 in my bedroom. I can't tell a difference and I don't have any apps really downloaded. I think if you game a lot the storage would come into play, but if you just watch tv and your apps are just for streaming various content, I think the 32 would have been fine.
 
Picked up a 32GB yesterday for $10 off at a local furniture/everything store here in Texas. I have had all the previous versions and this one is a great upgrade. The speed alone is a great upgrade. The remote is growing on me but can be finicky.

After downloading all my most frequently used apps, I am not anywhere even close to using up any space. Unless I really start gaming on this thing, 32GB is perfectly fine.

Right - I started using games and have filled 23gb so far... The good releases need around 2gb after downloading all the data. My 64gb will probably be full by March ;)
 
I got the 64gb version and I am using about 20gb with about 9 games. Mostly video. The games are what add storage. I have a live TV App and if tvOS now or later allows to store a queue(s) for using FF,REW, Pause then I could see a real need for the storage.
 
I got the 64GB version because my mom said she would get it for me for Christmas. Otherwise I might have gone with the 32GB version. Perhaps as more apps come out I will change my mind, but figure I might as well play it safe and heck, I didn't have to buy it. Thanks mom! Haha. Should last a good, long while. I just hate it when iOS devices get full and I have to do a bunch of management.

I don't think I'm using very much space yet but this racing game I got (I think it was Asphalt 8?) took a long time downloading additional files. I hope we get some racing games that don't feel so arcade-y. I like something closer to 75% sim 25% arcade. Fun but somewhat realistic. I think simple platformers and racing games will do well on this platform given the constraints of the remote. My mother-in-law bought me the Mad Catz C.T.R.L.i and it works with the TV and my iPhone, although some games like Minecraft are really screwy with the analog sticks.
 
I went 32 and am not anywhere near close to filling it up. Heck, I'm not anywhere near 16. There's such an awful selection of games and apps available that I don't see myself filling it ever. Mainly because to get the most out of any game, you really need a controller, which I'll never buy for the ATV4.
 
I intended to play games with the controller, so for me, the 64GB was the smarter choice. I've used up 20GB so far a few months in, so I made the right choice for my situation, and there aren't even that many good games yet.
