Google Maps is by far the strongest consumer product the company has to offer, and one of the most important online services, if not the most important online service of all. Google Maps was the reason I bought a smart phone. It is a revolutionary service, not only for navigation, but much more for finding restaurant and hotels, reviews and opening hours.
With that said, the interface is awful and laggy on all devices, and keeps changing.
Apple are total morons for not allowing crowd source of information on their maps. Business owners usually don't put their stuff there, and they think Instagram is a much better use of their time than having their adress and opening hours on Apple Maps.
