Have you tried parental controls on Android or are you just taking out of the side of your mouth? I have parental controls for my kids android devices and it works exceptionally well. I am not dissing the apple version because I have not used it, and based on your comment I have to assume you have not used the android parent controls and are just needing to convince yourself that apple are better and the apple premium you are paying is worth it.
What were the subpar controls? I use it daily for my kids so would genuinely like to know what you feel didn't/doesn't work because for the last 4 or 5 years I have never had one issue using it.
Spoiler: it isn't.
