My MiBox S came with Android 8.1. Should I update it to 9.0?

Do you think you have a reason for the upgrade? Missing something with 8.1 that you will get with ATV9? 

Not really because it's my first time using ATV in general. But maybe the update made some speed improvements or something like that. Guess I would stick with what it works then. Ty
