Amplifi is apples to oranges with their full setup.

I installed an Amplifi AP/Router at my parent's house. It works absolutely phenomenally for their use case, but is basically plug and play. The Ubiquiti gear is worlds more configurable.

which tends to fair poorly compared to orbi, asus, velop and others. a bottom of the pack product at the moment. its also not part of the unifi family, and doesnt have the advanced management interface.
