There's some items to watch for with Android tablets:
1) How important are updates? - You may get what you get and no security patches/updates/fixes.
2) Ensure that the brand/type you get includes the play store - some cheaper/lower-end ones may use alternative play store systems.
3) Check the CPU, RAM, and Storage - anymore 64GB of Storage may work, but I keep seeing something about Android doing a system volume or backup volume separate from the main volume. So 64GB, half may be for the other volume and the other half is the OS + installed apps? (Need to verify this). RAM, I would ensure at least 2GB for a tablet - especially if you want a screen with 1920x1080 or higher resolution. Even with a good CPU if you're lacking RAM, you'll notice.
4) Research the pre-installed apps on devices. I'm not sure what your use-case is, but sometimes the pre-installed apps can't be removed + may create security risks on the device.
