Google Android tracks you the most.

How do I even turn off location services without breaking Android Device Manager?

I have location history off but I still get notifications from maps that say things like "X place you're at is popular, click here to see reviews or something"

You've intentionally confused several things.

1. You don't need to use Android Device Manager. Unlike iOS, Android gives you a choice of device finders.

2. Location services is different from location history. Location services is an AGPS service that does not track anything tied to your account. iOS does the same thing, and worse, used to send your location to a third party AGPS provider (Skyhook).

3. Google Maps is separate from location history. Google Maps on iOS will tell you to see reviews as well, and it is a setting in both. Unlike on iOS, on Android, you have a choice not to use the default maps application at all and instead use an entirely offline map.

The above three points when support my initial claim that Android is a better privacy-focused system than iOS.

If it's Maps then I presume it is aware of Google's knowledge / collecting of hotspots and is then able to guess where you are. Probably some other voodoo as well. Point being, even with location off you're still trackable.

If you turned off wifi so you think that would help?

ha Android does not track you less than iOS and google can infer who you are using your ip address

And you have to 'activate' an iOS device with a SIM card. No such need for any android device.

Clearly not the case for Apple TV, which is the product being discussed here. See:

The only device that requires a SIM is an iPhone for obvious reasons.

And Apple is in the forefront of pushing for a integrated "SIM", effectively going back to the CDMA days...

Would this be similar to the eSIM in my Pixel 2 XL?

Yes

Is also worth remembering that all phones track you and that people who have access to the mast data can do stuff like this - https://ubicomplab.cs.washington.edu/pdfs/wibreathe.pdf
