I'd say initially it will be substandard in some ways, noting a lack of streetview for example, however it's very likely to receive constant updates to bring it into feature parity. Interestingly (or rather) surprisingly Apple maps already has 20M more business listings than Google. Apple maintaining robust business listings is required by Maps and Siri, which currently is lacking business listings outside of the USA. (The two are also an obvious pair for the user.) Both Google(Where2, ZipDash, Keyhole, Endoxon, ImageAmerica, Quiksee & Zagat) and Apple(Placebase, Poly9 & C3) have formed their mapping arms via acquisitions. Both companies are large and well resourced enough to innovate here. It's looking good for both platforms.
