Yes, Google Maps is superior in my region, but as I mentioned, I’d rather support Apple and DDG. I do so for their stances on privacy, but also because usability-wise I do prefer Apple Maps.

> I thought Apple Maps' data was just a subset of Google Maps'

They must be different datasets; I doubt Google would want to give Apple any data, or data Apple would take it. I will mention that once I have found one place in Apple Maps that was not in Google Maps. It was a small hostel in Europe.
