Agreed. If you are just looking at the core SmartTiles functionality then any OS works well.
As has been mentioned in other threads, Android offers a high degree of customization and there are some really cool setups that automatically light up tablets when a person walks up and some have voice command and voice announcement capabilities built in.
You can do some of these things in roundabout ways with iOS, but Android is really flexible for the tinkerer or “home hacker”.
