I have had various sticks and Roku highest end models and then got the latest ATV with hard wire port that adds Dolby vision and high frame rate HDR. I have a 2022 high-end TV.

The video quality is noticeably better. Not sure of older ATV, but this is clearly better than the top end Roku. Also, I’m not sure if it is the same on older tvs

The other thing is that you want to hard wire if at all possible. Even the best wifi can’t touch the reliability of a wire

You do realize that they are actually tracking the device itself by the hardware MAC address and other device fingerprints.

The email is just a bonus to let them legally spam you. Anti-spam laws have an exemption. If there’s a prior business relationship like shopping in their stores, they can put you on their spam list unless you opt out.

Bogus email only helps for spam but doesn’t do anything about tracking.

EDIT: For Android when there’s a Captive Portal like the screen shot. devices will use Persistent randomization which while not the hardware MAC will remain the same for the same network where they can track your visits.
