It depends a bit on where I am. I rarely use maps in North America, as I'm always visiting someone and never have a car. My default is apple maps, but I can't swear to its current accuracy in Canada or the US.
Here in Europe, I've found google maps WAY less reliable for finding addresses. In the UK, if I want to go to a postcode, it's only 50/50 that google getting me to the right place, where as I haven't had issues with a postcode in apple maps in years. That said, in Spain, if it's a weird address, or an address with more than one possible spelling, sometimes Apple will just give up, or will try to direct me to Madrid (I'm in Salamanca).
It's been 3 years, but when I lived in Paris during lockdown, Google again had weird issues sending to places that could be blocks away, because they had the numbering wrong. I didn't have that issue with apple maps, but apple maps didn't have cycling directions at the time, and their pedestrian directions could be straight up dangerous on a bike if I wasn't paying attention.
So I use both, and have issues with both, but my default preference today, in 2024, is Apple as it is more consistently reliable.
As for restaurant reviews, I use neither. I have never had a bad experience with a restaurant booked on The Fork / La Fourchette.
