Here in Europe Apple Maps is now great for travelling between cities.
But within historic cities with many winding streets and strange obstacles Waze is absolutely the way to go. It picks out creative shortcuts all of the time that neither Apple nor Google come close to (they just route down the main throughfares, even if they are at a standstill), and it's also kind of important that it picks out speed traps and other obstacles with remarkable timeliness and accuracy.
An interesting thought on crowdsourced mapping. Obviously it's the only way to get sudden updates when something "happens". But have been wondering if it's the only risk-free way a large maps provider can provide creative backstreet routing. Meaning, if the computer calculates a better but "highly original" route then there is a chance that there'll be an unforeseen problem with it. Now if you're Waze, you'll discover that pretty quickly because you'll see users bouncing back out the way they came. But if you're Apple or Google you're going to continue sending people down a "bad" route, potentially causing chaos on a massive scale. So, in other words, the big mapping providers are never going to risk being creative with their routing. 🙁 That's my theory anyway!
