Exaggerated sweeping statements aren’t helpful to anyone. In my experience Google Maps is much better at finding businesses, whereas Apple Maps is better at finding residential addresses.
Half the time if I search a business on Apple Maps, it hasn’t heard of it, most of the time I type a specific house number on Google Maps, it takes me to the wrong end of the street, and upon zooming in you realise barely 1 in 10 houses on that street have numbers on GMaps.
Because of this I tend to use both to compliment each apps shortcomings.
