It's not perfect in the US.... but neither was Google. Apple has worked better for me.
As a Google user we got bad info all the time and shrugged it off--it was still awesome for the 95% good info! But slap an Apple logo on an error and suddenly it's a war crime
I thought I'd miss Street View but I don't: blurry, awkward, and so... slow...
Exploring a neighborhood in fast-gliding Flyover (where available) is so much nicer for the same purposes. Except reading small signs... which Street View allows maybe half the time at best?
I'm imagining if Google Maps had had Flyover all along, and not Street View. Then imagine Apple came out with Street View as it exists: awkward to navigate, slow to load, full of glitches, double images, blurs, blinding sun flares and noisy shadows. Click... move 20 feet. Click... move 20 feet. Apple would be a laughing stock! But since Apple did NOT make Street View, bloggers pretend it's the greatest thing since sliced bread.
And it was useful, and still is where Flyover is missing. But not that great.
And now, for future improvements: Apple's getting a ton of mapping data that Google is no longer receiving.
