Hi @BAllen9674 ,
I do understand that you have three products to choose the best and better parental control.
It depends on the features that these parental control software includes within it. However as the Verizon is you native network provider and if the parental control is preinstalled. It should have more privilege then the other third party application. Even-though iPhone have it own parental control features, it may not have more options like other parental control software's .
Also having all these together will conflict and may fail in filtering contents.
