Just been checking my own house.
Google aerial imaging is very good and up to date. Apple is aerial imaging very good but about a year or so behind. (There is some building going on nearby which makes it easy to see.)
But Google roads are dreadful. About 15 years out of date for my actual house/road. My entire bit of road is missing - it should feed about 15 houses. And I can see the discrepancies between the aerial image and Google's own map!
Another bit of the road carries on about 100 yards where it doesn't, and never will, exist! Almost every day we get people (typically delivery drivers) thinking they can drive up that bit of road. We have to explain and they have to drive about a mile and a half to get where they want to go!
In the small image you can see a diagonal finger of road going over private driveway, garden and bare earth. (It's not obvious, but there is a 'cliff' of about 15 feet in height. And it ends in a lake - currently dry.) And the road in the bottom right is simply ignored.
Twice submitted corrections to Google - but no changes have been made.
Apple maps for this area are well within three metres/ten feet of spot on. Air tags, Find My, navigation - all absolutely right.
