I'm not sure what it's like in other parts of the country but from the south east cost these are my experiences so far:
A huge swathe of the south east has no aerial photography whatsoever beyond a satellite level where contrails are clearly visible.
I tried requesting a route from my current location to a nearby train station and it gave me a route to a random pub in the next town over - this was for a search term that worked reliably in the old maps app.
Maps themselves show much less information than the equivalent google maps view. There's a fraction of the POI's available and those that are available are often 100m+ off from their actual location.
